Army Armament R26 1911 replica Two tone blue/black

Pistol is gas blow back.. Has never been used in the field, has only been used occasionally for shooting targets in the garden. WARNING: Magazine leaks gas slowly over time, not sure if this is an easy fix as i’m not knowledgeable in airsoft. Originally got this pistol for £115 so have discounted it heavily due to the magazine issue. Open to offers
