Spare Metal CO2 Magazine for Umarex H&K USP Airsoft Pistol

"An excellent magazine full metal

"Great mag over all ! It gets the job done a tad bit pricey compared to the gun ( buying extra two mags is around the same as price for non blow back pistol it self) its metal and seals great . mine has no signs of leakage ( after having it for 8 months and using it everyother weekend) be advised theres locking port at the bottom on thr mag so you have to hold down the spring using the slide and if you let go all the bbs will fly righy out and you have to repeat the process of reloading it. It comes with an allen wrench to . since its metal it give your usp a heavier feel . to me thats a pro

"Considering the utter cheapness of this gun you may be wondering "should I just buy another 1" the answer is no. And here's why. Have you ever wanted to just hit the mag release and have the mag hollywoodily fall out? For you may now achieve this for the low price of $25.

Pros
-heavy
-holds seal good
-won't cross thread

Con's
-almost the price of the gun
