Great 1911 for you..
So I have Rock Island GI model 1911 (I only like mil-spec GI 1911's even though I would not consider RI to be mil-spec). I have put 10,000 rounds through it without any issues BUT for a few hundred more dollars you can have a very GREAT 1911. Rock Island has a cast frame and maybe even the slide which is not as good as Springfields forged frame and slide. I suggest you go with the Stainless Springfield 1911A1, I think they put a little more care into the stainless model for some reason. If you do go with Springfield make sure it has a 1 piece barrel which it should if it is Stainless and make sure it says Geneseo IL, so you know it was assembled here in the US. All Springer 1911's start their life in Brazil in a very good machine plant. So I like to tinker or replace lesser quality parts with better parts, so as of now (at first it was all wilson combat parts) I kept the stock Springfield ignition (trigger) system, although MIM parts exist they are of high quality and will last a long time, however I did replace all the pins with the Ed Brown 1911 rebuild kit. The pins were tighter than the stock Springfield pins-meaning less slop, meaning less wear and unneccessary play. I fitted a Wilson Combat BP extractor, my Springfield did not come with the ILS (look that up) it came with a stock main spring housing which is what you want so I am using a 23lb hammer spring. The feed ramp is already polished and chamber is reamed or polished I cannot remember, but no failures with the exception of a magazine related one so I replaced the follower and that fixed that. Google Springfield 1911 torture test and you will find a page about a Springfield 1911 with like over 150,000 rounds through it. I replace my recoil spring every 2000 rounds along with the hammer spring and firing pin spring. That is a little overboard but its my EDC and I am a high volume shooter.
