When purchasing Nowlin or any other brand from eGoods365.com store, you can be sure that (a) you are purchasing from US based company with the most responsive and friendly customer service; (b) an authentic, not a counterfeit and not a refurbished product.

These super match-grade barrels are not "drop in," so the gunsmith can precisely fit them to a specific slide/receiver pair for the tightest lockup and best accuracy results.  They come short chambered, so reaming to achieve correct headspace is required, as is fitting of the hood, lugs and feet. But the special geometry of Nowlin's pre-cut top lugs typically requires only minor fitting to achieve maximum lug engagement. Groove and bore tolerances are held to an amazing .0002" via state-of-the-art electro-discharge cathode maching (ECM), and rifling is ultra-smooth, uniform and precise. Smooth-cut rifling boosts velocity, while the unique angled edge on the driving band gives a better gas seal for reduced fouling with all types of bullets, plus longer barrel life. Puts extra weight where you need it most, right at the muzzle for controlling recoil and helping get a faster follow-up shot.  Keeps the front sight down and on target.  Replaces bushing and increases lockup area for improved accuracy.
