Lone Wolf Distributors porting delivers optimum performance in muzzle control. This 4 port system positively improves your ability to keep on target during rapid fire by redirecting the gases upward, thereby forcing the muzzle down, keeping you "on target".

Custom 4 port external (outside the length of the slide) barrel porting. Two smaller ports and then two larger ports towards the end of the barrel. Ports are EDM cut for precision and a nice, clean look.

  • Fits Glock 17,22,31,20&21 with 6" barrels. You MUST have 6" barrels to have enough room for the ports.

  • There must be 1 5/8" length between the end of the slide and the crown of the barrel in order to fit 4 ports.

  • Porting can take up to 3 weeks.

  • We only offer this service on Glock pistols.

  • If porting a black oxide barrel we must do the porting first, so order a silver barrel and black oxide instead of ordering an already blacked barrel.

  • Not available for .460 Rowland.

  • If you plan on ordering a barrel and having it ported, please add this part number along with your items.

  • If you plan on sending in your own barrel for porting, please call 208-448-0600 and have a representative process your order.

***We do not accept Glock OEM, AlphaWolf, or non-LWD slides or barrels for porting***

An unacceptable percentage of factory slides & barrels have been noted to contain bits of carbon. During the porting process, an electrode could come into contact with this carbon and blow out the port. LWD Stainless steel barrels or slides are not subject to carbon blow outs.
