i plan on changing soon to a glock 31 probably with Federal 125gr Hydra-Shocks and an M3 or sure-fire light. (of course i first have to get the gun; which i hope is soon).
Although I have a Gold Cup and a GP100 the pistol I have nearest is my Sig 230 - .380.
I have shot it so much and have become so familiar with it that I KNOW I have a better chance getting hits with it than my other handguns.It fits in my hand so well, and it points like another finger.The .380 gets back on target a little quicker than the bigger calibers.It keeps me covered between my bed and the closet my 12 gauge is in!
Any good gun in 9mm or above, that can be shot accuratly and reliably.... the max round or gun I would use would be a .45 "Long Colt", a potent proven killer that has mild recoil... Posse up!
