I have a Lama Commander, but my kid has a really nice pre-A! 1911 made in 1919 IIRC.
it is so worn that you have to watch out when you are racking it in case the slide pin falls out!!
This gun has had a zillion rounds through it, even has three tally marks on the trigger guard!
We have taken the slid and barrel, and have put them on a few Norincos , and everything cycled with no issues whatsoever!
He also has two race guns, but they are
(1) 2011's
(2) IPSC open class abominations!
Dunno if you catch the drift, but unless it's a stocker, I ain't interested!!
