There are a lot of good guns, as has been mentioned, Browning and Beretta tend to be the most popular, but most important, is that it fits, not just length of pull, but drop at comb is just as important, and cast also needs to be checked. Gas operated semi autos produce the least felt recoil, and the more established, and common brands tend to be the easiest to get parts for in 5-10 years, whereas the cheap Turkish brands often change every year or two, and parts can be an issue.
