Wrong Caliber Sent
The first one I received was for a 40 or 45. I couldn't get it to pull a round or a spent cartridge from the chamber. First I thought it was the extractor but after looking at it further, it wouldn't hold a 9mm case. Customer service was awesome. They quickly sent out a label to return it and sent out one that works flawlessly. couldn't be happier.
USShe’s purdy
And works like a mule. Dropped right in my Aero Precision EPC-9 and never missed a beat.
