The comp is a must on the Glock conversions. It delays the action opening and slows down the slide. I have ran the .45 Super and currently the .460 Rowland. If you are staying within pressure specs the Rowland has a sizable energy advantage. The super running in a 6" unvented barrel would spit 185grs at 1325fps safely. The Rowland will launch the same bullet nearly 1700fps. The Rowland will launch 230grs 1450fps. The 265gr Beartooths will leave the tube at 1300+. reflex264

"A quiet hit in the right place is better than a loud miss in the wrong place followed by 10 more shots on the run"

I was a handgun hunter, when handgun wasn't cool.....
