So after finding a complete CS40 kit, minus receiver, on GB in January, I decided to send the barrel to Bill, BMCM, for his magic and I am more than impressed.
I waited a few weeks to post my review on this conversion because I wanted to put 500 rounds down range first.
Out of those rounds I never had any malfunctions. I tried everything from CCI aluminum cased ammo to high end Hornady Critical Duty 175.
My reloads had the best accuracy at 20 yards.
The most difficult part of this conversion is getting the mag gutted and getting the 10mm follower sanded down on the sides to fit the last round perfectly.
A big thanks to Bill for all his work on the barrel.
This gun carries great!
