All handguns, whether they're semi-automatics, revolvers or single-shot guns, either use a hammer or a striker to set off the projectile. But what's the difference? The simplest way you can tell them apart is that if you can see a hammer at the end of the slide, it's a hammer-fire. Striker-fired guns never have a visible widget there. Some revolvers have a "concealed" hammer, but if it's a revolver, it's always a hammer-fire. (If you'd like more information about the difference, don't miss this great article from our friends at NRA Women!)
Does it make a difference when it comes to concealed carry? Well, the short answer is a "yes" with a "but," and the long answer is a "no" with an "and." In this great (and very brief) video from Shooting Illustrated's Kevin Creighton, you'll learn about CCW with a hammer-fired pistol, and why many people choose to carry them for personal protection.
