Why the Glock pistol? I believe it is due to the proven reliability track record. But what I feel is most important is the the simple design of the pistol.... anyone can feel comfortable working on the pistol by themselves. It is this comfort level on working on the pistol that allow even the mechanically challenged to take a proactive approach in doing preventative maintenance (with out having to find a gunsmith). Also the simple design of the pistol allow most anyone to understand exactly how the pistol works on the inside. All of this translates to having more confidence in the Glock pistol. I just bought a CZ75 pistol recently. It's probably my favorite pistol as of today. However, much to my dismay I have come to the conclusion this afternoon, after much soul searching, that I will be carrying my Glock 19 instead of the CZ. It all has to do with confidence with the pistol. I understand how the parts the Glock pistol work and is CZ pistol not so much. This of course may change as I tinker around the CZ. Once I learn to change out the springs...I may start carrying it. But for now, it's the Glock.
