I have about 20,000 rounds through my 20 year old Delta. It is stock, no modifications, and mostly hot reloads. Used it as a woods gun, dropped behind the seat, fallen off a skidder many times, cleaned a few times a year, and it never broke or fell apart (I did loose a grip screw somewhere). It has been a good tool. I just got a Glock 20 that will get the same treatment. I don’t care what parts it shares with other guns, it just plain works. I don’t pamper my tools, I make them work for me and I got my moneys worth out of the Delta.
P.S. It's cold here.
