Lone Wolf Distributors is able to perform factory style porting on any Glock OEM slide or barrel. However, it is not recommended. The customer assumes and accepts all risk involved in this process at the time of order. EDM porting of OEM parts involves the possibility of an electrode contacting a carbon deposit below the metal surface, which interrupts the flow of electricity, causing molten metal to “blow out” around the carbon deposit, ruining the part. This defect has affected up to 10% of all OEM parts, LWD will offer a similar part if available at a fair price. Glock OEM parts will not be replaced.

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 internal (inside the length of the slide) barrel porting. 2 ports are smaller; then towards the end of the slide, there are two larger ports. Ports are EDM cut for precision and a nice clean look.

  • Available for all LWD stainless steel barrels (LWD) or Glock OEM with customer disclaimer acknowledged
  • Lead time for porting can take up to 3 weeks
  • This item is for porting a barrel only, if you'd like to port a slide also click here
  • Any custom porting requests that are outside of the stock port services we offer, will double in price and must be approved prior to custom work being done
  • If your slide already has a coffin cutout but it's not a Glock OEM cut the slide must be sent in to match the barrel porting. 
  • Compact and subcompact models do not have enough room for 4 port internal porting

  • If you plan on sending in your own barrel for porting, please call 208-448-0600 and have a representative process your order
  • If porting a coated barrel (black oxide barrel, cerakote, or PVD), it will require refinishing (see refinishing options here)
  • Any custom porting requests that are outside of the stock port services we offer, will double in price and must be approved prior to custom work being done.

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.
