Do not worry the galling problem occurred in 1970s to early 80s affecting companies like AMT. Stainless 1911s made now do not have this problem.
There is no need to compromise by settling for 10mm in 1911. There are numerous choices now: S&W, Glock, XD, SiG (with SAO action option?), Tanfoglio.
I've seen new Delta Elites jamb up at their first range session. The owner cleans the new gun up to make it pretty, then runs it almost dry with their Hot loads.
...and to keep the fight going... I'd venture to say nobody forges a frame/slide better than COLT or their suppliers.
