Took the Glock 20 out for the first time today. As always I want to change out the factory sights. Aside from that I ran 50 200 grain rounds through it. I forget what they were. I picked them up for $13 they were relatively light loads. I put 10 Hornady 155 grain jhp's supposedly pushing 1265 fps through it just to make sure they would feed without issue for carry purposes. The gun functioned flawlessly and I will be blowing out the x at tactical range as soon as I change out the sights. I love it. Now I also took out the ruger sp101 and ran a box of American eagle 158 grain. 357 magnums through it. I picked them up for $20. Honestly I like the gun but the sights and grip are terrible. I'm lucky to be in the black with it and the two guys I let try it were lucky to hit the target. One of the guys fired one shot and put it down. The other said it's terrible and grabbed his patrolman for me to try. That gun is fantastic I put all 6 shots in the x easily. Anyway to rap it up the ruger bruised the crap out of my hand but I kept shooting it until the box was empty.
