Could use some advise, I bought 3, 10 round magazines and converted then to 25 where it is legal in my state. Had to buy load assist buttons as the ones I bought had none on it. These are the aluminum ones and fit loosely on the magazines. The bolt will not hold open after last shot fired with these magazines but a factory 10 round magazine I own will hold the bolt open every time after last shot fired. Any ideas would be appreciated. I love this gun and want it running flawlessly 😁
