Got a Glock 22 with over 100,000 round's now and i have never had one problem with it. My Glock 19 is soon approaching that amount as well. My hk uspc has close to 20,000 round's and only one stove pipe. All my sig's just under 10,000 and not a problem. The only gun i ever had a problem with was my xd first 200 round's in it had a few failure's to feed and a few stove pipe's that is why it no longer remain's in my collection.
