I have purchased this mag twice now and have been very impressed with the accuracy it adds to my Body Guard .380. This second one has been not been staying in with certain ammo not sure what is going on but it pops out with each round fired. When I use different ammo it works OK my first one functions fine with any ammo. One good thing is if I use HP,s it is no problem, so I will see as time goes on if it still malfunctions with the cheaper FMJ's ammo.
