Introducing the World’s Highest Precision Barrel

Our new Tru-Axis™ precision barrels are made using a revolutionary single-point rifling system in which one machine comprehensively crafts every part of the barrel from start to finish. The rifling alone is done with over one hundred fifty miniscule cuts! This method induces no stress to be relieved later and is ultra-accurate, even after normal machine tool wear. The result is a precision barrel with perfect concentricity between chamber, free-bore and rifling, a very uniform twist rate, and rifling grooves with a deviation of less than one ten thousandth of an inch from groove depth to groove depth.

Tru-Axis™ precision barrels are made in the U.S.A., feature a fully supported chamber body, and have an 11-degree muzzle crown. Each barrel is magnetic particle checked for microscopic cracks, hand polished to a mirror finish, and then protected with our industry best titanium-nitride coating.

Here at Lionheart, we believe you should have options to make your pistol exactly how you want it to be! Therefore, our Tru-Axis™ precision barrels come in three different colors and are available in standard and threaded variants. In addition to providing top of the line wear resistance, our titanium-nitride coating comes in your choice of gold, black, or grey. Threaded barrels come with ½ – 28 right-hand threading that is protected by our signature engraved diamond cap.

Our all-new Tru-Axis™ Precision 9mm Barrels are machined to perfection giving you amazing accuracy.  We’ve even coated the barrels in ultra-hard Titanium Nitride – in THREE color choices.  Choose from the threaded, suppressor-ready option with diamond-machined thread protector cap, or standard and head to the range to see the results!

Your new Tru-Axis™ barrel’s bore and chamber are not coated with our titanium nitride coating which armors its outer surfaces.  This allows for a proper break-in and to ensure the highest possible accuracy (bore comes pre-oiled to prevent corrosion).

If you are using a threaded barrel be sure to test your suppressor to recoil rod clearance before firing the first time by slowly hand racking the slide.  We test all the main brands but it never hurts to check!

  • Barrels fit the DP-51, DP-51C, LH-Series, and Regulus Series pistols.

    Wow!! This barrel is incredible! It dropped into my MKII like a glove and has run flawlessly since day 1! I love the gold finish, it really adds a classy touch to my pistol. The accuracy is excellent, I’ve got about 250 rounds through it so far and every shot has been exactly where I wanted it. This barrel is markedly different from the old barrel in a few key areas, and those changes definitely are for the better. One change I’m really happy about is that the guide-rod notch is cut much deeper; I always felt it was too shallow on the original barrel and I’m glad to see they thought so too! I can’t wait to get a suppressor on the end of this and make use of the threading I have waited so long for! Great job Lionheart!!
