For EDC, a larger dot of 6, 8 or even 10 MOA in diameter will serve your purposes much better than the currently popular smaller dots of 1, 2 or 3 MOA. The reasons are almost infinite, but some more obvious than others.

Assuming time is of the essence when engaging an adversary with your EDC pistol, the speed with which the red dot can be located and superimposed over the target is of supreme importance. The bigger the dot, the easier it is to find and direct to the target. Some may argue that a big dot is not as accurate as a small dot, therefore might not be as effective because it covers too much of the target. Let’s stop and examine that thinking by doing a little math.

A 10-MOA dot covers roughly a 10-inch diameter area at 100 yards. That subtends down to 5 inches at 50 yards, 2.5 inches at 25 yards and 1 inch at 10 yards.

I won’t judge another person’s shot-delivery capabilities under the stress of a life-or-death situation, but it would seem that a 10-MOA dot would be sufficient when considering the statistical data of the encounter being in close proximity. For the average citizen, my definition of close proximity can be thought of as the inability to escape the situation, making the use of a deadly weapon the only available choice to prevent grave bodily harm or death. This is not legal advice, just my perspective. Keep in mind that time and distance almost always have an impact on one another during a dynamic event.

I don’t know.  Based on the pictures presented of various dot sizes, I don’t like the large ones.  I don’t really have a hard time picking up iron sights.  I’m not sure how that translates to red dots.

What size do readers carry, and why?

You can also purchase a new slide or have a current one machined to anchor without adapter intervention. Rival Arms, a Texas-based firm with an enviable reputation for that service, explained, “We offer two different optic cuts, RMR and DOC. The RMR cut, as you can imagine, is the same optic cut as the Trijicon RMR sight and will also work with other optics that follow this footprint (Trijicon SRO, Holosun 507c, Swampfox Kingslayer, TruGlo TRU-Tec Micro RMR variant, etc.). The DOC refers to Docter Optic footprint/setscrew pattern, which is compatible with the following popular sights: Vortex Viper [and] Venom, Burris FastFire, etc.”

I’ve noticed that this is beginning to be a real problem in the gun industry, i.e., choosing the right mounting option for pistol sights.

Here is another interesting article, more detailed and much more technical, entitled Footprints/Mounting Standards on Red Dot Sights.  I catalog this sort of thing just for you, the reader.

You’re welcome.  Enjoy.  Share thoughts.

The only one I’m somewhat familiar with is the Holosun.  The Holosun is quickly gaining a very good reputation.  But where are the FDE models?  They don’t exist.

If you want a FDE model, you have to go with the Trijicon RMR.

John appears to like the Holosun, and it’s cheaper than the competitors.

I did a little time with a pistol red dot sight on Saturday for the first time, and reflexively looked for the front post and tried to co-witness it with the dot.  That’s wrong, but breaking that habit will be tough if I get a pistol red dot sight.  I’ll need to spend some time turning training time into muscle memory.
