Pretty sure a 200 round break-in is recommended with all 1911s. A slight polish on the feed-ramp might be in order, and I’d stay away from anything flat-nosed, for self defense.
My favorite is a 1928 commercial model…beautiful old 1911 that is 97 years old…it functions perfectly…however I like my G21 as well…
Or we could just get something that works out of the factory.
I only bother to polish ramps when it actually makes an effort to function. I’m well aware of the 200-300 round break in period, but more often than not, in my experience, their reliability deteriorates. The exceptions to this were the Ruger and the rock island models, though not all. I’ve seen decent homebrews some of our students cobbled together
