Hey Mark,
There's a reason Brownell's screws are cheaper and come with four in a pack...They suck... I put Brownell's in my gun after I changed grips the first time, and when I went to put on my Hogue grips, the head of the screw busted off. Needless to say, I didn't put the extra pair of Brownell's into my pistol (CZ75B .40). I got new screws from Hogue, and they work and look awesome. If I were you Abwehr, I wouldn't put Brownell's in my gun.
