  1. As a point of clarification, we make 9MM lowers that work with Glock style magazines, and we make 9MM lowers that work with Colt style magazines. The same lower will NOT work with both. It is an EITHER/OR situation. Not a one size fits all. Hope that helps.

  2. So how did it run? I have a psa 9mm stripped lower o bought a while back. I’m trying to decide if I should build a psa 9mm carbine or go with a Ruger 9mm carbine or a kel etc sub2000. This will be used for steel challenge. Getting sick of all those pcc guys winning.

  3. I know whats coming next. AR9 pistol. They are addictive. And the cost of ammo makes it fun all day long. I recommend 8"-11" put a SB Tactical brace on it and it will be your favorite gun to shoot. Great review. PSA rocks.

  4. Do you think cmmg’s 9mm delayed blowback Barrel/bcg would work with PSA’s billet lower? I thought about doing a frankenbuild to keep the cost down and get the positives to eventually suppress. Thanks! God bless RWB
