Not perfect but close 06/10/2018
This adapter is fantastic. The pistol I used fed reliably from all the Glock mags that fit in the well, including 40 S&W and 357 SIG magazines. Installation and adjustment is a matter of turning in one screw to set it, and then two more for standoffs so it doesn't move around when you seat a new magazine.
The only reason I took off a star is because the mag release is a little awkward to use, the thing was very sticky with an aftermarket 9mm drum magazine, and the bolt hold open was a little hyper aggressive and held the bolt open with one still in the magazine.
Awesome 21/08/2018
Been looking for a reliable 9mm conversion for almost a year and after tons of researches (forum and YT), I decided to bite the bullet and purchase Stern Defense.
I have to say this thing is amazing, I installed this to my Anderson lower and it fits perfectly no play and nothing. To be on the safe side, I purchased Stern Defense Upper (from their website) paired with their H3 Buffer.
Went to the range today and shot 1000rounds and ZERO hiccup! I ran all kinds of ammo (freedommunitions 115/147gn, Fiocchi 115gn, and Sellier&Bellot 115gn)
All and all, I'm very satisfied with the product!
