If it's an consolation, there's guys doing this with real open guns in the very low 3's. Yes this is a welfare open gun, but the only advantage I see is the mini magwell and the red dot. The gun handling is the challenge on this test, and body can shoot two to the head in sub 2, and .20 splits to the A zone aren't even fast with a bone stock Glock.
I don't think using the Roland special would be much of a gain in THIS test. I'd love for some people to shoot this with just a red dot and then again with the magic compensator.
