1911s are finicky to say the least!!! There are so many variables that can effect how they run (or won't run). Anything from ammo selection to magazines to extractor tuning and anything in between can cause reliability issues. I have found that they are a very individualistic platform, meaning you can buy 2 identical 1911s off the shelf and one of them can have reliability issues, the other perfect. Find one you like, test it with the ammo you like, if a no go, change mags, ammo or both. If still a no go, start trouble shooting in more detail.

I have built several myself, from rebuilding a factory gun to building a full custom. So far (knock on wood) never had to give up on one.
