True Precision Barrel Features The True Precision Barrel is machined from 416R stainless steel billet a premium material chosen for its strength and corrosion resistance in a match grade drop-in barrel. The proprietary broach cut 6 groove rifling is engineered to increase accuracy potential while safely handling cast lead and all common factory ammo types. An improved and widened feed ramp over the stock barrel helps hollow point and defensive ammunition feed more reliably which matters for anyone carrying this pistol for self defense.

An 11 degree target crown helps protect the rifling at the muzzle and supports consistent accuracy shot after shot. The SAAMI spec chamber ensures proper fit and reliable function with quality 9mm ammunition.
