Brand new, just tested function. 2 standard mags. Neither leak but the release valve is weak. Dumps all gas in 7 shots on both. Replace both valves you have 2 mags for less than half. 1 extended mag no leaks Removable compensator with threaded barrel underneath 14mil negative. Really like the pistol just not what I thought as I was after getting it. Shipping and PayPal fees included in price. Only swaps would be a 19x, 45ct, or a CZ variant. Can add cash depending on deal Thanks!
