Barrels listed as “In Stock” are machined per order specifications from customer.  Barrels are made drop in or fitted, cut to length, and crowned per order.  For this reason, please allow 2-4 weeks for your order to be filled and shipped.  If a barrel is listed as “On Backorder”, it means we are currently manufacturing a run of these barrels and do not have any in inventory.  You may place an order, which will place you on our backorder list, and we will fill and ship your order as soon as we are finished manufacturing.

We now offer custom PVD finish options.  Our Glock barrels are now available in our standard black finish as well as silver and copper PVD coatings. PVD (Physical Vapor Deposition) coatings are an extremely hard coating that offer aesthetically pleasing colors and increased lubricity.  Our CrN PVD coating is a silver finish similar to that of stainless steel.  Our TiCN PVD coating is a satin copper.  For colors, please see images at the top of the page.  PLEASE NOTE THAT PVD FINISHES ADD APPROXIMATELY 2-3 WEEKS TO LEAD TIME.

1 review for GLOCK 34 BARREL

  1. Michael Pistone (verified owner)

    This is my second or third Jarvis barrel. This Glock 34 barrel is going in a custom Glock and when it came to having a ported barrel made, my first pick was a Jarvis Match Grade Barrel. I had to send in my slide for correct fitting of the ports. The Slide was returned in absolutely perfect condition (as I would expect from these folks) and the fit of the barrel is superb!.

    When you purchase a Jarvis barrel you are purchasing accuracy from a true professional.
