I went the cheap route since I wasn't sure I would even use it. I ordered from Bear Creek and got it for $47 shipped. Just tried it with the 40 cal mags and went bang every time. I didn't shoot for target but it did hit a 18" square of cardboard from 25 feet. I fast fired the last 4 rounds and they were all low on the cardboard. Not match grade but works fine. Now I need thread protector for it. Didn't see it offered from them, but they should have "suggested" it for POS reasons.
