Every time I think about getting a decent pistol I always migrate to .45, the “man stopper”. But Frankly, 9mm ammo is so relatively cheap and plentiful that I’m thinking that, unless you are a “gun enthusiast”, 9mm is simply a no brainer. And getting 18 shots to a magazine is hard to beat.
I’m 45 free. 9mm and 38/357mag only with a smattering of 22 for good measure.
