    Rohm

    Could be the reg seal or the hammer valve. Try some soapy water or worst case dunk it in a bowl of water.

    By the way magicniner is also on this bbs.

    If the cylinder holds air OK off the gun the firing valve seat is the most likely area for a leak.
    A full strip, clean and relube of the firing valve may well sort it unless a seal has physical damage, stripping, cleaning & relubing the reg is worth doing whilst the pistol is apart.
    Clean all components thoroughly and lightly coat only the O rings with silicone grease,

    I'm very pleased to say that both my experiences of crossed threads were after the deed had been done
    I strongly suggest that anyone not confident of their abilities in stripping & rebuilding seek assistance, it's easy to scrap a frame if you make incorrect assumptions,
