i don't know that much about guns but i know a little bit. anyway i turn 21 next month and have been trying to decide what type of gun to buy. i've been thinking about the STI tactical, or maybe the STI eagle 6.0 in either .45ACP or .38 super. however i'm going to want a suppressor and i was wondering if i can get the barrel threaded on most guns or are there only certain types that can be fitted with a suppressor? Also what are your opinions on the guns i mentioned? if you don't think highly of these guns, please feel free to reccomend something better for me. i like 1911 style guns, lightrails are good, threaded barrel, drilled/skeletonized trigger/hammer, low recoil, at least a .38 super caliber. i'd like something accurate, reliable, stylish, and i'm willing to pay for quality. also, where can i buy high capacity magazines. like a 170mm 20 round .45 cal mag. or a 170mm 27 rd .38 super magazine or something close to that capacity? i checked gunbroker and a few other sites to no avail. i've been looking around and reading gun magazines, i've shot a few friends guns trying to see what i like but i just don't really know where to look. STI guns seem to be the best that i can find but if you know anything better please let me know. i have 2 guns already a browning and a ruger, both in .22lr so its not really a "whats a good first gun" thread. i kinda know what i want but i just wanted to get some opinions from you guys. so please help me out.
