I have had a Glock 29sf for a lomg time, and it is a fantastic shooter. I just went to the range and shot some Buffalo Bore 220 gr/1200 FPS/703 ft lbs. (a little less from the 29) It kicked more than the regular stuff but still was quite manageable at self defense distances. I would not try anything else but a Glock. I am a soccer for reliability when it comes to firearms. I wish there were an XD, HK, SIG or FN in 10mm, but until then, among the choices given, I stay with the Glock. In fact I am a looking for a G20 4th G now (hard to find).
