My .02
Best depends:
-For pocket carry (in some pants) a J frame is "better" than a 380. How? 5 shots for sure with more KE per shot. Revolver will shoot dry & dirty.
-For not into guns people: people who want a gun but are going to just shoot a few rounds and then keep the gun by the bed or stuck some other place with limited additional practice or interest, definitely a revolver.
-For people who limp wrist guns: revolver
I gave three examples of why a revolver might be better. Now I'll give reasons why I carry a pistol
-One exception: the only time I carry a revolver is pocket carry with some pants, in other pants I have to go with the 380 becuse it's lighter and slimmer.
-I only carry concealed (never open carry) and pistols are
easier to conceal than revolvers (assuming revolver is bigger than a J frame).
-
Increased capacity,
larger bore size and / or greater KE per shot (compared to J frame). Glock 27 is one heck of a compact package providing concealibility, capacity and power all in one.
Although pistols can and do malfunction, the ones I carry have proven themselves reliable. I only carry ammo that I've tested in that particular pistol. If a magazine spring seems weak compared to a new one I replace it even though the pistol still currently funuctions with it (prevention).
I prefer a semiauto for a bedside gun as well, Glock 38. Night sights,
rail mounted light, big bore (45) plus 9 rounds gives me comfort. I guess the model 32 (357 Sig) would also be acceptable; 14 rounds with 357 mag levels of power.
