Will not function in suppressed g45 or 19x - Tyrant CNC Threaded Barrel Pistol Barrel

They function normally just fine but are slightly to short and they will not all the gun to cycle or function properly during suppressed shooting. Tried both a g45 and 19x and 3 different cans with 3 different pistons etc. Perhaps mine is just that 1 but when you advertise drop in ready they should be tested prior to being sold.
