I have 2 Glocks, a 17L (9mm) for the range and a 37 (45 GAP) for the nightstand...both have been problem free, easy to use and parts/accessories are readily available.
I'm impressed enough to seriously consider a model 38 (45 GAP in a 19 size package) as a carry gun...I'll save the 629 for short range hunting.
