My first one was a DCM gun my folks bought from the original purchaser for $25 bucks and gave to me for Christmas, 1962. Have had a few more since then.
Sprung for an SA stainless mil-spec a year or so ago; now have about 850 rounds of my RNL handloads through it and it has been a good gun. Reliable, decent trigger, accurate. Anything can break but right now this one looks like a winner.
In contrast I recently sent a polymer-framed .45 ACP that allegedly never acts up back to the mfr. After 1200 plus rounds and one trip in for factory voodoo it still averaged 32 rds between malfunctions. The factory will destroy it and replace it with a new one--which I intend to sell NIB and try to forget.
I too miss the old GI pistols, but without a time machine with heavy lifting capability those days are gone. The SA has met my stringent expectations thus far.
