I'm in the market for a new semi-auto handgun. The only handgun I own is a Rugger .22, but I'm thinking about getting a larger caliber gun like a 9mm or a .45. I really like the looks and feel of the 1911's, and I also like the Glock 17. I will use this gun for taget shooting and home defence. Concidering all of the new handguns out there, what would be a few to look into. I would like the price to be under $500 if possilbe. What about ammo, isn't the 9mm a bunch cheaper than .45 ammo? What would you recomend? Thanks.
