It's fragile!! - ProMag Glock 17/19 9mm Luger 50 Round Pistol Magazine

I bought one of these in FDE and was using it in a 9mm pcc as well as a g45. I only fired one drum through it before it had a catastrophic malfunction. The pcc was leaning against the wall with the mag inserted and it fell over and the drum snapped clean off the tower and sprayed 9mm subs across my floor. I contacted Optics Planet and they referred me to Promag tech support, who uad me return the mag (supposedly so their engineers could look at it to determine how to fix the issue going forward) for a replacement. It was not too much of a hassle, but more than i would have liked. The real problem is the replacement mag did exactly the same thing within a couple months. I never even used it. The 1st time i loaded it up i put it in a g45 and i had a misfeed so i tapped the mag (tap rack bang) and the drum snapped off the tower and sprayed 40+ rounds everywhere. Exact same spot it broke before. There is something wrong with the polymer the tower is made out of because it broke at the lip that locks it to the drum both times. I will include pictures if possible. Would not recommend this one. I do have some promag stick style glock mags that work fine, but this drum is just too fragile. Spend a few extra dollars and get the pmag drum instead. I havent been able to get them on the phone yet, but i will update this with the outcome of the customer service process.
