How many Magazines do you have for it ? Could that be the problem ?
Just a thought, because the BuckMark I had ran great but I bought a replacement mag for it (supposedly factory ) and had many failures to feed only with that mag.
I'm not biased because they pay me or b/c I'm a Glock Ninja or anything like that...... It comes from my own personal experience with the guns and the extreme reliability that I have witnessed -- for a personal defense gun, reliability is #1 on my list of criteria.
Death, Taxes, and Glocks will go bang every single time!
Just busting your chops Eric. If I were going to buy a Double action Semi Auto it would be a Glock.
