Wow, I've been away for a few years and there seems to be hundreds of categories. I hope this is the correct one for my post. (p.s., since I last posted here, I added a G27 to my collection. I also added a LaRue Tactical 5.56 OBR, a real tack driver. 0.25 moa at 100 yd. with my handloaded mk262 clones) I was at the range last week, shooting my Glock 22, when the guy on the next range noticed me eyeing his pistol and offered to let me shoot it. Didn't seem to have noticably increased felt recoil over the 40 S&W. He said it was a Glock 21, with a KKM barrel (w/ a huge compensator, four side ports and two on top) and .45 Super. He claimed to have hung out with some Delta guys his last trip to Afghanistan. He said that that was what they were shooting, so he made one for himself. It did shoot nice. My questions abound. With just having met the guy, I had no way of knowing 1) if he had really spent any time around Delta guys, 2) if that is truly what they were shooting, and 3) if that gun was really loaded with .45 Super. He claimed that shooting .45 ACP, the compensator was mostly ineffective, but that with .45 Super, it seemed to largely eliminate muzzle flip. Everyone I have spoken to since has had their doubtsrofl. I even wrote to KKM and their reponse was a predictable, "our barrels are the finest blah blah blah, and are capable of shooting 45 Super, but a Glock would not be our first pick..." What does everyone here think? Is there a possibility that the guy was completely truthful? Partially truthful? I was all set to make one of these myself until I encountered all the skepticism. Could it work?
