i am tempted myself even though i doubt they are USA made. they look an awful lot like the ones SARCO sells and they are PI.
don't matter all that much where they came from.
what does matter is that there 'good" ones with out some horrible flaw that is going to send shrapnel to your face!
it might be worth a shot. they got one review where some guy put one on a essex frame. that don't carry much weight with me either.
somebody should try one so we all know--
on their ar stuff some love them and some hate them.
i generally avoid anything AR-15 related to this company in any of its various names. i have seen a couple of very off spec uppers that came from them. i figure not all their stuff could be that far off and they still be in the biz. i just don't like going to the races with something that can blow up in my face if it ain't correctly made.
these 1911 parts could be OK. if there like everything "hesse" some of them are probably good, some are probably workable and some are --well you get the idea.
others have bought AK and other rifle stuff from them and so far everyone seems happy enough so maybe these 1911 parts will be like their AK stuff--
