Is this compatible with the Sig M18 LCI?

Manufacturer Answer
A
Answered by Dan GGP, Manufacturer from ID, United States, on March 06, 2025

Hello, no our barrels do not have the cutout for the LCI in M18's and M17's, the barrels will still function normally in the slides, but the LCI parts will need to be removed. Thanks!

The Grey Ghost Precision Match SIG P320 Compact Threaded Pistol Barrel is for compact Sig P320 models and will not fit the Sig P320 XFive Legion. Unfortunately we do not have a threaded barrel for the Sig P320 XFive.
