In the days of yore, I've had Gold Cups/ Clark's/ Chows and issue NM pistols.
I guess .... IMO...Clark did the best work. Ones I have in 45 now are a couple of Auto Ordinance that I fitted slides to frames, polished guts and fitted match barrels/bushings and triggers to. (Skeet, the early ones were machined and can be bought cheap!!!)They shoot a LOT better than the ole goat is capable of!LOL
Dang, it's amazing how much less ya shoot when uncle is not feeding them!
