    Cant wait to try this new barrel out on my P365XL. Hopefully I find a new silencer to test this new barrel out with. Happy for the purchase.

    A great product all around , from an exceptional company. I was able to confidently buy this threaded barrel for my Sig365XL. Went with the gold TiN and am 100% satisfied. It looks phenomenal and preforms really well. Those looking to shoot suppressed , this is the way. These things go out of stock really quick so if you’re on the fence , I would definitely would pull the trigger. Also, the shipping was incredibly quick. I would highly recommend to a friend!

    Sig P365XL Threaded Barrel

    Posted by Tom Walter on Nov 2nd 2021

    Cut very nicely and finished well without burrs , ragged cuts, or unfinished areas. The barrel was finished with attention to details, especially around the barrel stop and breech. Fit was "drop-in" as noted, without play in the frame or slide. Exceptional product.

    Amost perfect.

    It would be great if this was offered in a shorter option like some other barrel makers. I use a micro comp on it over a CAM-LOK adapter for easy switching to cans. This barrel length offering leaves a lot of barrel (about 1/2") exposed beyond the slide in that configuration. Other than that, its a great solid and accurate barrel that looks great!
