Glocks are the most durable, reliable and versatile weapons that I have tried. I say this having owned around 25 pistols of all types and brand names.
Not to mention they have the best service policy in the industry. If you have a problem with your Glock, they will fix it no matter what. Warranty or no warranty, no questions asked.
In fact I have a Glock that I've fired over 15,000 times with so few failures that I could count them on one hand.
I also have had excellent results from Ruger, Smith and Wesson, and Colt.
