Threaded Extension


SKU: N/A Categories/Brands: ,


Common for most popular Glocks Sigs M&Ps etc. Please send your slide with the barrel so we can match the depth/diameter of the extension. We can NOT thread Glock barrels made after 2014. This service is only for 9mm or .22 barrels with an OD of at least 1/2″. This service can only be done on pistols with removable barrels. We do NOT remove pressed in barrels such as PPKs P7M8s etc..

The thread pitch used to attach the extension is selected at our discretion. Each piece is made to match(concentric) the specific barrel it was made for. You will not be able to thread multiple barrels and use the same extension. This is for safety as well as reliability reasons.

With some firearms, the threaded extension must be removed to field strip the weapon.

Turn around for this service is 7-10 business days.
