The Glock issue isn't "the Gospel according to Kyle", I assure you all. It is a known problem and though there are hundreds of owners who have never had a problem, there are tens of thousands of Glocks out there. I used to ship an average of 8 Glocks per week back to the factory in Georgia for repairs, and whenever there was a call for assistance on the range it was usually trouble with a jammed Glock. Their inherent weaknesses include, but are not limited to, the internal striker system and their magazines. You may never have a problem with yours, and like you said...you somehow managed to get a Sig to jam (as most guns out of the box are mechanical problems waiting to happen), but by and large, the Glock is not a comfortable choice for self defense. Most law enforcement agencies bought it for the same reason that the Military went with the Beretta over the Sig...PRICE. Glock undercut everyone in a brilliant marketing strategy that made them rich, but it supplied agencies with years of problems. At the range, I lost count of how many defective magazines we returned to Glock and how many cracked slides we came across. I am talking in the realm of hundreds of guns over the space of 18 months, so it isn't my opinion alone. These things are known to many people but not often published.
The story is the same with the M16s since the day they were introduced, but we still use them, too. It isn't quality, but price that dictates such things.
By the way, I am not just a Glock hater! I have owned and extensively fired almost 100 handguns, plus more if you count those I have fired but not actually owned. Of ALL of them, the only guns to never once give me any trouble were a Sig P220 in .45, a Browning Hi Power in 9mm, and an HK P7M8. Everything else, in some form or another, came up shallow. Ironically, I don't own any of the three presently. Always on the lookout for the "perfect" handgun.
In the end, if I am going to place my life and the lives of others in the hands of firearms engineers, I am going to be extremely picky. As a part of a larger collection I have no quarrels with the Glock. They can be fun to shoot. But I do not recommend them for home defense, defensive carry, or as a primary weapon for any purpose other than plinking.
Sorry for the novel, but handguns are something of a passion for me, and I spend (and have spent) thousands of dollars and countless hours in study and hands on experimenting, as well as work related experience to gain my knowledge.
One day we'll dive into submachine guns...my second passion. No time or room for that here!
