The Umarex (VFC) 30rds Magazine for Umarex UMP9 GBB SMG is a polymer encased metal construction magazine for the Umarex UMP9 GBB SMG series and holds 30 rounds of BBs. Green gas only. If you own a Umarex UMP45 gas blowback rifle, then this UMP9 gas magazine will also work with your gun. The gas magazines of the UMP45 and UMP9 are interchangeable.
I ordered 2 of these for my umarex UMP45 GBB, they're supposed to fit but for me they didn't so I guess only get these if you have a UMP9.
The mags feel like they are very good quality with great materials. The mags are very very heavy though, so sticking 5 of these in your vest can get very heavy very quick.

This UMP9 Magazine does fit my UMP45 GBB
Fits my UMP45 GBB fine and functions perfectly. Very well made, It is a heavy mag which helps to make the UMP feel more like a real one. Love it.
Fast shipping to US and well packed.
