Field strip your pistol as you would for cleaning & maintenance

Slide the barrel sleeve onto the barrel until it is approximately 12mm / 1/2” from the breech block with the cut-out at the bottom.

(For later guns ensure the cut-out is aligned with the anti-tamper weld and slide the sleeve all the way on to ensure the cut-out clears the weld and allows the sleeve to touch the breech block, remove additional material with a file if required to clear the weld then pull the sleeve 12mm /1/2” away from the breech block. )


Apply bonding compound all around this edge then push fully into position


Apply a generous bead of sleeve bonding compound around the breech end edge of the sleeve, including the cut-out.


Push the sleeve slowly into place and once it is firmly against the breech block wipe off any excess bonding compound with kitchen roll, tissue or an absorbent rag.


Now hold the barrel vertical with the muzzle upwards,

Where to apply bonding compound 

Apply bonding compound around ¾ of the sleeve – barrel join, this will allow compound to be drawn by capiliary action into the interface between barrel and sleeve to provide a solid bond.

Add more compound as that already applied flows into the joint, after a minute apply compound to the last ¼ of the join to ensure the compound completes the circle fully.


Allow the barrel to stand upright for 15 minutes then wipe off any remaining excess compound and allow to stand for a further 30 minutes for the compound to set before reassembling the pistol.

A correctly fitting barrel bushing allowing negligible in-battery slide wobble.
