I have my 20SF all set up with my lone wolf steel guide rod and Glock factory 6inch barrel. This morning i put 80 silvertips through it and a box of blazers. Didn't have time to chrono anything but the longer barrel seemed to tame the hell out of the recoil. Hits on the 12" steel gong at 100 yards were easy, and that thing really swung on a hit. Flawless functioning. I love this pistol. I will post pics as soon as i can. P.S. to the board member who asked about whether its time to get out of the 10mm i say don't- its a versatile high powered and accurate round. Wanna kill these ads? We can help!
