Hi guys here is my Hk PX4 Custom gas blowback. Great pistol has a polymer lower with metal slide & internals, it’s basically a WE PX4 with full trades that had to be re branded for licensing purposes due to the trade marks. So completely compatible with WE and can use TM or WE mags / parts. 
Has a good kick to it shoots great at 320 FPS no issues. Everything works perfectly locks back on empty, safety ect. 

comes in its box with back straps & a IMI defence lockable retention holster, has been freshly serviced & cleaned. 
Looking for £70.00 collected from Birmingham or £75.00 posted.
