I shoot a open glock 17 in 9 major and its competitive. My open glock runs like a top. I run Dawson extensions with a Dawson ice mag well. I think the secret to running a glock successfully in open is all in the loads. As far as recoil in the video of gaming goddess, It looks to me like the 9x21 she shot recoiled and choked just as much as the glock she was shooting, possibly due to her grip and not so much the fault of either gun. No matter what you shoot, you do your part and the gun will do its part. Just goggle Jessie Abbate or Dave Sevigny
Good luck, Joe
