Work but far from ideal
Tho this magazine works and functions 100% like it should in a regular p320 that's where it ends... my Magwell is to snug for magazine, AR mag block it won't even lock in. Upon closer inspection where magazine lock sticks out over 16th of an inch over factory magazine Pros: Cheap Cons: Wrong dimensions

Don't do it! They don't work!
I bought two of these for use in my X-5. Neither one would let the gun cycle properly. You have to remove the magazine for the gun to finish cycling and to reset the trigger. This goes beyond just a quality control problem to being a manufacturing flaw. ProMag needs to get their act together.

2 magazine's neither function
I bought Two of these 32 round magazine's and all they do is fail. The pistol will not cycle. One of two problems, either it won't eject the spent round, of the trigger won't reset. You have to drop the clip for the trigger to reset. What's the point in a 32 round magazine you have to take out after every shot. Both malfunction in the same way, that's not hit or miss, that bad manufacturing or design!! STAY AWAY!!!!! Cons: Does not work

Did not work with my Sig Sauer P320.
ProMag magazines are a Hit-or-Miss. In this case, this was a big miss. I tried this magazine at the range yesterday afternoon and could not fire more than three consecutive rounds without having some sort of issue. I should mention I am meticulous with the cleanliness and condition of my pistols and, regardless, the magazine malfunctioned. I tried 4 different kinds of ammunition; loading the magazine to full capacity, half capacity and down to just 5 rounds at the time and nothing worked. I also tried an extended, 15-round Pro-Mag magazine for a Ruger P90 and those failed as well but, in all fairness, I tried two magazines for my Sig Sauer P938 and those worked without any problems. Again, ProMag magazines can be Hit-or-Miss. My advice would be to order one, try it and see how it works with your particular pistol.
