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.
