I recently decided I need to start consolidating my calibers a bit. I have decided I want to have one caliber that is my primary caliber of choice. After a bit of think I have decided that caliber will be .40S&W for me. Why? Because it is a powerful round and I am very competent with it. It is also available in such a wide variety of firearms that I feel that I can fill almost every niche with that caliber. This is how I have ended up covering my bases with the .40S&W round... Light Work Carry: Kahr PM40 Heavy Work/Summer Carry: Glock 27 Winter Carry: Sig P229 Elite Glove Box Backup: Springfield XD-40SC Survival Bag Gun: H&K USPc Bi-tone This way I feel I can start stocking one primary ammo more than the others. I can also just keep a couple bozes of .40S&W in my survival bag in my trunk and I will have ammo for what-ever gun I happen to have on me at the time. Don't get me wrong. I will still stock other caliber ammo and keep other caliber guns. I am a firm believer of having a little of everything. You always need to have a gun that will work with whatever ammo you are likely to find in a rough spot. It is just that now I can train with and keep available to myself a standard. Anyone else do this?
