Hey I've been researching things online and I think I'm going to go with a semiauto for home defense... although there's a problem. I want it to be stainless/silver finish, and have a tactical rail for a light. I haven't been able to find any that fit this description. As far as caliber goes, it seems as if 9mm or .357 are the cheapest for ammunition, and .40 and .45 are more expensive, correct?
The Taurus 24/7 Pro comes in a stainless steel finish w/ light rail. It only comes in 9mm, .40S&W, and .45ACP. I believe the .357Sig round is closer in price to .40S&W per 100 in winchester white box ammo. I hope this helps.
