I have had 3 barrels made for H&K pistols from Jarvis. Even though I am on the other side of the United States the communication, shipping and product delivered have been excellent. I would not hesitate to use again or recommend to someone who needs a barrel.

Bought a custom threaded barrel for my USP Expert. The barrel is extremely high quality, and quite similar to the factory one. It functioned great and was quite accurate. Would definitely buy from them again.

They were extremely helpful! I had purchased a HK USP45 with a threaded barrel that the original owner had purchased from Jarvis. The thread protector was missing and he did not know the thread pitch. I contacted Jarvis and they went above and beyond to determine the thread pitch and ship a new thread protector to me. Great service.

Reliability and Accuracy.  The two most important features of any firearm.  Every day we come to work with the same purpose.  That is to create the most accurate barrels available without sacrificing the reliability of your firearm.

All of our barrels are manufactured with US steel, heat treated to 40-42 HRC, with critical dimensions machined to .0005″ tolerances.  They are conventionally rifled to a mirror finish with the button rifling process to shoot both lead and jacketed bullets.  Chamber, groove and bore diameters are held to optimal dimensions with tolerances of .0005″ to ensure repeatability with every pull of the trigger.

For 40 years custom pistol barrels have been our daily focus. Our skilled team of Engineers, Gunsmiths, and Machine Operators carry out every step and manufacturing process from loading the steel off the truck to shipping the product out the door to you.  Our daily goal is to exceed our customer’s expectations and work with you to provide you with the best barrel available.

Barrel Threading and Customization


Customization is important to the end user and we strive to provide you with as many options as possible.  We offer a wide range of threading options per caliber for suppressor or compensator use.  We also offer customer specified barrel lengths from factory length up to 6.02″ for most pistol models we offer with multiple porting styles available.

Both drop-In and fitted options are available for all of our pistol barrels.  Our drop-in barrels are made to do just that; drop into your gun and function accurately and reliably.  For the customer that desires the tightest lockup possible, we offer barrel fitting which can be performed by us or the customer if desired.  1911’s and the Beretta M9/92 platform require the complete firearm for fitting.  All other barrels require the slide only.
