High quality threaded barrel for Sig P226

I actually haven't shot the new barrel yet but the quality/finish appears to be equal to or better than OEM. It does come with a thread protector too.

Great Barrel

Bought this to replace the barrel that came with my P226 Legion. I will be mounting a SilencerCo Osprey 9 To it whenever my approval comes back This barrel did come with a thread protector. Fit and function is excellent. Put a few rounds through it over the weekend and accuracy appears to be the same as the original barrel. So far Im please with it.

Great replacement barrel

Bought this to replace a .40 cal barrel in my P226 to change over to 9mm. Barrel swapped right in with no fitment necessary. The finish on the barrel is outstanding. Haven't tried it on the range yet, but I can't imagine any issues will come up.
