Is it safe to use +P ammunition with this barrel?

Manufacturer Answer

Answered by MVL, Manufacturer from AR, United States, on October 20, 2026

Yes, Wilson Combat Glock barrels are rated for +P ammunition.
These aftermarket barrels feature a fully supported chamber, are machined from high-strength 416R stainless steel, and are heat-treated to an R/C 40 hardness rating to safely handle the higher pressures of SAAMI-compliant +P rounds.

SHOTgun 1, guest, from NY, United States, asked on April 06, 2025

I would like to know if the Glock 34 gen 4 Wilson barrel is a drop in version . I purchased one from Wilson before.

Manufacturer Answer

Answered by MVL, Manufacturer from AR, United States, on October 21, 2026

This is compatible with the Glock 34 Gen 4.
Wilson Combat barrels may require minor fitting and should only be installed by a qualified gunsmith. Although these barrels are intended to be drop-in, some fitting may be necessary. We highly recommend all fitting/installation of barrels is done by a professional gunsmith.
