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.
