100 rounds through the G30. 0 issues and shot like a dream. Love the trigger on this weapon. Approx 50 rounds of 9mm through the S&W 59. 0 issues and this gun also has a wonderful trigger although different from the G30. My son and I put about 200 rounds through the Buckmark. 0 issues and this thing is so accurate it always puts a big grin on my face. My wife mostly shot the G19 so she can practice for her chl. She put about 150 through it. 0 issues other than she probably took about 20-25 brass shots to the face. I shot about 75 rounds rounds myself and got hit about 10 times with brass. I also experienced 2 stovepipes. This only the second time Ive shot this gun. Put 100 rounds through it when I bought it new last week. No problems then. Anyone got any advice on this? All ammo was winchester white box from walmart except. 22 was cci mini mags.
