I am a FFL Gun dealer in VT and I love all my Glock Pistols. Can someone tell me how well Glock 30's and Glock 33's stand up to high volumes of shooting. I have been asked this question by a guy who wants to buy a G30 and G33. His concern is if the frame will stand up to lots and lots of rounds. I just sold him 2000 rounds of .357 Sig Ammo and 3500 rounds of .45 acp. He wants to shoot all of that plus order more ammo. He now owns Sigs but likes what he hears about Glocks. Are there issues with these 2 models after many rounds??
