When an extended barrel is necessary AWC acquires these barrels 1 inch longer than standard, cuts and re-crowns to proper length, properly threads the barrel, & fabricates a thread protector.
Accurately machined and suppressor tuned match grade stainless steel barrels are available for Beretta, Browning, Colt, Glock, Para Ordnance, Sig, S&W M&P, Springfield Armory XD, Walther and others.
Since many weapons vary in tolerances some Semi-Drop in barrels will need to be fitted by a knowledgeable certified gunsmith. AWC performs fitting services for $55.00 which includes fitting the barrel to the pistol and function testing the pistol with and without the suppressor.
