I like finding resources like this. Actually, reddit/Firearms is the source, and this comment was insightful.

Easiest way to check the forcing cone for wear is to put a straight edge on it (if you see light from a gap, it has some erosion – not necessarily an issue) and to run a q-tip around it to see if there are any burrs (the burrs will pull off strands of cotton).

Offhand, I would say that one looks pretty much new.

My first GP100 was bought well used and easily has 25k-35k rounds of handloads, including a ton of rapid fire (~900-1000 rounds in an hour and a half or so, barrel was literally too hot to hold) nuclear bear loads. Even with the forcing cone eroded a bit it will still shoot about a <4″ group at 100 yards.

The cylinder wear timing mark looks normal – GP100 / Redhawk / Security Six actions lift the cylinder stop pin into place relatively early to ensure it drops fully into the cylinder notch during rapid fire.

Pro tip to smooth out the trigger pull as a novice without messing with the sear:

1. Take the hammer strut and smooth & polish the top and sides to mirror finish, then lube with grease – many of the factory guns are under lubed and may have burrs left from the factory (giveaway in the gunshop is if you hear a squeak when cocking the hammer).
2. Deburr the trigger return spring / trigger guard latch hole and the trigger return plunger. These often have a burr.
3. Polish the sides of the hammer and frame window where the hammer pivots to remove burrs – you can tell if this is necessary if there are rub or scrape marks on the sides of the hammer.

Then later in the comments, located on Google drive, is a more complete description of revolver checkout. If you have any resources yourself, feel free to drop them in the comments.

I always think it’s slightly amusing when folks rediscover wheel guns. My favorite comment is this.

People have successfully defended their lives with snub nose revolvers for 100+ years. You can too.

I do carry pocket revolvers and I think they’re a wonderful alternative to either OWB (which is non-permissive at times) or IWB (which I hate), and more accessible than ankle carry.

But as with any weapon, you’re only going to be as good as your practice. I would rather shoot single action because the trigger is as tactile as a 1911, but if I carry a wheel gun to the range, I always make sure to shoot a couple of cylinders in double action.

I’ve shot a lot of rounds through wheel guns, and I guess I’d never thought much about these things.

AllOutdoor:

A recent article in a second-class gun magazine reviewed several handguns that were introduced at the 2017 SHOT Show in Las Vegas. The author called revolvers “antiquated technology on par with the manual typewriter,” but went on to state that despite this, American gun consumers simply cannot get enough of them. He was certainly correct on that account.

If anything, revolvers are just as popular today as ever, if not moreso given the introductions of new, exciting models from major gun manufacturers. If these wheel guns did not sell, why would gun makers continue to produce them? In fact, they cannot keep up with demand for new revolvers.

Now, to be fair, that author is just another millennial type who was not raised on wheel guns. These guys grew up on cable TV, tofu, sushi, MTV, X-Boxes, and sports drinks. They go all goo-goo for pistols. The more switches and buttons to push, the better. Just the sound of a racking slide makes them break out in goose bumps.

Trying to describe the practical aspects of a revolver, the fun and beauty of the timing of a hammer cocking to align with a loaded cylinder chamber is like trying to talk about a 1955 Ford Thunderbird or a Chevy SS with a 396 under the hood. That guy probably drives an electric car.

I recently spoke to a gun store employee who said the same thing.  There has been a rediscovery of revolvers within the past year to two.  I hope I’ve been in some small way responsible for that in my own little circle of readers.  I commented to him that there is no reason that the revolver should ever become obsolete.

He shrugged and said, “And they’re a ton of fun to shoot!”  Well, yes, more fun than pistols, but I agree with the author.  It’s more than that.  It’s the beauty of the machine, the precision of the action, the gorgeous build of the gun, the feel of the “purchase,” and the sweet, light trigger in single action.

And don’t discount the reliability factor either.  Finally, the small gap between the cylinder and forcing cone means that rounds that cannot be handled in most pistols (excepting the VERY large and heavy Desert Eagle) can be handled in revolvers, up to and including 500 S&W.  You cannot achieve 1400 FPS with a 9mm pistol because of chamber pressure, but you can with a .357 magnum wheel gun.

I did the plastic (polymer) gun scene, and sold them all for 1911s and revolvers.  Revolvers are only passé to immature, pea brain millennials who have no appreciation for the finer things.

Shooting Illustrated has a very informative article on revolver disassembly and cleaning.  It’s worth reading in full, and it’s also worth sending this link to yourself and referring to it later with an email search (which is what I do).

It has very good pictures (I learn visually) and also recommendations for revolver tools.  I’ll be using this advice in the future.  If anyone has additional counsel for revolver disassembly, maintenance or cleaning, please fill in the details in comments.

Outdoor Life:

In today’s world of high-capacity, polymer-frame, semi-auto pistols, we often forget about the original repeating handgun. While the roots of the revolver go back to the revolving arquebus, produced by Hans Stopler of Nuremberg in 1597, it wasn’t until 1836 that Sam Colt figured out how to make it work reliably. Once Colt started making revolvers, the world of repeating handguns changed forever.

Whether you’re in the field hunting, hiking, or exploring, or in any wilderness setting, the revolver is the top choice in a handgun. For personal defense, the double-action revolver may be a bit less popular nowadays, but it’s every bit as good a choice as it ever was.

I agree.  I have one concealed carry revolver, and two that are too big to conceal, requiring open carry.  I carry my small wheel gun regularly.  And while we’re on the subject of revolvers again, Lucky Gunner has a nice article on testing the Ruger GP100.  I love mine.  But that’s not what caught my eye.  While reading the Outdoor Life piece on carry revolvers, I noticed one I missed from two years ago that has some remarkable anecdotal data.

Even here in Alaska, where you’d think we would have the “bear sidearm” thing figured out, all you have to do is mention bear protection in a crowded place or online forum, and you will no doubt hear from numerous people who swear on their mother’s grave that their .44 mag, .454, .500, or other monster caliber is the ideal bear protection. I have however, only heard one claim myself of someone stopping a grizzly with one shot from a .460. The bigger-is-better idea is rapidly going the way of the buffalo, and here’s why.

I’ll say this very clearly. No handgun has the energy to drop a bear in its tracks (barring a perfect, or extremely lucky shot). Even the .500 S&W has little more energy than a .30-30. If you read John Snow’s blog last week, you saw a scientific comparison of several autoloading cartridges and the conclusions that the FBI drew from it. Yes, the bigger cartridges do slightly more damage than a .45 ACP, but we are talking about animals that can sometimes soak up .375 H&H rounds like they are BB’s. I’ve personally witnessed a brown bear take 13 solid shots from less than 20 yards with a .375 Ackley before it expired. I have seen black bears shot at under 15 yards with .338’s and 7mm Mag’s and not even lose their footing. The handgun is a last resort, slightly better than nothing. Never, EVER rely on a handgun as your primary defense if you know you are going to be in a risky situation. Take a large rifle you are comfortable with, or a shotgun.

[ … ]

I think that with a heavy wheelgun, you will get one shot off if you are lucky. If you’re wondering how you would do, next time you are at the range, see how many hits you can get on a 15” x 20” target at 15 feet in 3 seconds (including drawing from your carry holster). You probably won’t have much more time than that in the field, and possibly less.

Select your backcountry sidearm wisely, and be safe out there!

Okay, I hear you loud and clear.  But it’s still the case that soon after firearms were declared legal in national parks a man defended his life from a grizzly in Denali National Par using a .45 ACP handgun.  I always want more rather than less, but I’ll take what I’ve got and try to aim well if this situation ever presents itself.  I’m not sure that anyone can ever be truly prepared for an attack like this save doing it all of the time.

Lucky Gunner recently had a great article on Revolver Velocity Versus Barrel Length that I missed, and I recommend that you spend a couple of minutes studying their results.

Their results might surprise you.  First of all, barrel length doesn’t matter as much as you might have thought, perhaps as much as 100 FPS for barrel lengths in the range we normally carry or shoot.  You have to get really long barrels (such as for hunting) for the length to make any substantial difference.

Second, the +P loads do actually give you noticeably better performance (as much as 100 FPS or more) compared to the regular loads.

Third, as good as the +P loads do compared to .39 Special, they don’t compare to the difference you get with the .357 Magnum, which is as much as several hundred FPS depending upon bullet weight.

Lucky Gunner recommend that you test your own loads, guns and bullet weights if you want an accurate assessment.  They also link this article where a table is included that has good data for your consideration.

Shooting Illustrated:

A miniature 9 mm also offers you the advantages of the same manual of arms your larger gun. If you’re used to a striker-fired gun, the operation of the Ruger LC9s or Glock G43 will seem like second nature to you, just like the operation of snub-nosed revolvers mimic the operation of their larger cousins. My fingers goes naturally to the magazine release on my 9 mm Smith & Wesson Shield because that’s where it is on the large semi-automatic pistols that I occasionally carry, and the methods I use to clear malfunctions are pretty much the same between those guns as well.

The reasons to carry a subcompact, single-stack 9 mm over a larger pistol are also essentially the same as reasons to carry a small revolver instead of full-sized gun. With the right holster and appropriate cover garment, it’s fairly easy to discretely carry a full-size 9 mm on a daily basis and without tipping people off that you’re carrying a pistol with you. However, it’s even easier to conceal a smaller gun, and a smaller gun also opens other options like pocket carry that are even more discreet.

When it comes to defensive applications, the subcompact single stack 9 mm has several advantages over snub-nosed revolvers. The thinner, slimmer design of the semi-automatic means it can slide into locations for concealed carry that aren’t available to thicker, bulkier revolvers, although, counter-intuitively, I’ve found that unless you pay attention to holster choice, a small .38 Spl. revolver forms an indistinct lump in a front pocket that’s easily mistaken for a wallet and keys, while the flatter, more angular form of a mini 9 mm sticks out and says “gun” more readily.

Another advantage of a mini 9 mm over small revolver is ammunition capacity. Subcompact single stacks typically have at least six rounds of ammunition in the magazine and one more in the chamber, and extended magazine that pack in eight rounds or more are not uncommon, By comparison, six rounds is maximum amount of ammo in most pocket revolvers, with five rounds being the most-common option available.

I’ll grant the point about capacity, as well as the ability quickly to reload.  But for those of us whose hands don’t readily shoot the small subcompact with accuracy, and who simply do not run the gun well, it makes no difference.  Sometimes these arguments are semantic and pale in comparison to whether you can operate the system and hit what you’re aiming at.  As to whether I can conceal a smallish .38 Special revolver, I have no problem at all keeping my air weight S&W wheel gun on my ankle or anywhere else.

And I never worry about whether a round is chambered, or whether it will work when it’s supposed to.  A round is ready, and it will work.  I know that without a doubt.  The wheel gun will never go out of style.  It may be that I carry it as a backup gun to a 1911 on my hip, or sometimes I have to carry only it depending upon circumstances.  But I will always carry a wheel gun, regardless of what LEOs choose to do.

My goodness.  I do love me a good wheel gun.  I do indeed.  There’s just a feel of the machinery and a tactile connection with the revolver that I don’t get with the plastic guns, and perhaps even the 1911, which is probably my favorite platform.

Advocating concealed carry of small revolvers for self defense.  He’s got a good point about all of the lint.

This is interesting.  Rob Leatham wins the USPSA revolver championship.  I’ve always thought of him as a pistol guy.  Congratulations to Rob.  I wish I was as good as he is.  But I do have a question.  Look at this grip he’s using.

It looks like he’s using a grip customary for pistols rather than revolvers, where he is putting the thumb of his left hand near the forcing cone where it could get injured.  I don’t suspect for a minute that Rob Leatham visits the pages of this blog, but could someone explain what he’s doing and why it’s okay?

Well, I guess I didn’t see this one coming.  Kydex holsters for a number of different revolver designs.

When revolvers had safeties.  Hmm … don’t think I like the idea.  No, not at all.

Ruger SP101 review.  Ruger is making very nice revolvers these days, and I would carry this gun for personal defense in a heartbeat.  It doesn’t look nearly as pretty as the Ruger GP100 Match Champion, but then again, you can’t conceal a GP100 Match Champion.  I do think they should have made the entire grip that nice looking wood rather than embedding it in the rubber grips.

I still want someone – anyone – with personal knowledge to give me a story of someone in OIF or OEF (Iraq or Afghanistan theaters) carrying a revolver rather than a pistol.
