I carry a Glock 21 daily to protect me and my family( of course all of my other hand guns are S&W's). All my other guns are S&W's I have never seen one in person go BOOM! I have a friend who is a C3/C7 so he get Post Sample MG's and we beat on them. He had a Glock 18 that he put 30,000 rounds thru in two years, he had a handful of FTF's, but no BOOMs!
