Mag Wobble CA UMC (UMP)
 

Just bought a brand new Classic Army UMC. Very awesome, I love it, but it's got mag wobble. Can this be fixed (other than shoving soft velcro in there)? Would this warrant and exchange from where I purchased it from? I love the gun, but I'm bummed out that it has this issue.

I had one too. Mag was also wobbly. I used some electrical tape to shim up the mag well. Perhaps someone on here knows a brand of mags that fit well in the gun
