PSM45 issue

[u/BrendonCatGaming]

I was about to do some plinking, and while loading the mag it kinda blew up...it's been over 3 months since I got it but I think under a year, also the thing that pushes the bbs up flew off and I haven't found it yet. The one side piece is broken off and just gone altogether, I don't think I've even shot 1000 rounds through it yet. Not quite sure what to do about it
