Not all magazines have these issues showcased in this video. We are sharing some of the things we check when we have malfunctions and isolated the magazine to be the cause. I use similar principles to troubleshoot and diagnose the AR.
Some may wonder why we modified the front of the magazine since the bullet will hit the barrels feed ramps and raise. With some ammunition that's true, but with more pointed ammo like Hornady Critical Duty/Defense the pointed projectiles they use don't always behave like a typical 9mm profiled projectile does.
We didn't show issues with the plastic flashing on the inside of the magazines in this video. To remove the flashing, I used a surgical scalpel and some 800 grit sandpaper to knock down the flashing. The flashing can cause the rounds or follower to hang up. Several of these magazines had this issue.
Some people have experienced issues with these magazines not locking the slide back. In some cases the shooters grip can cause this, in other cases the follower misses the slide release. This can be a spring/follower issues, or an aftermarket slide release compatibility issue. I normally suggest testing with a factory slide stop and switch shooting hands to make sure the grip isn't holding down the slide release and the aftermarket slide release isn't the culprit.
We also didn't discuss baseplate flex when the magazines are left loaded. Hopefully PSA makes a beefier baseplate or an aftermarket option comes to the market.
Beyond the baseplate issue, these particular mags have been running flawlessly. I will keep my eye on the springs to make sure they don't take an excessive "set" and cause problems.
