Our department switched over to Glock .40s this month. Shot about 150 rounds through mine today at the range. I was a little diappointed considering all the good things I have heard about Glock. Recoil was a bit more harsh than our previous pistols, Smith/Wesson .40s. I think it is because the Glock is lighter? Anyhow, my hand was a little sore after shooting...I have never had this happen before. The slide of the Glock was pretty slippery when we were doing malfunction drills. The slide slipped out of my hand a couple times. I think I am going to have to invest in some Hogue grips and some aftermarket slide attachments to make this pistol work for me. What ever happend to the days of a good old Colt 1911 or a Colt Python?
