Excellent quality by Gary, Verified Owner, April 6, 2024
At the time I couldn't find a factory sig barrel anywhere. I thought that I would try it. Very nice fit and different look. Because it was fluted.

All threading barrels come with a thread protector.

Industry standard is 150 rounds to break in a barrel before threading any device on to the barrel.

When a barrel contains the word "conversion", it means these barrels work only in 40S&W and .357 converting to 9mm.

You cannot go from a 9mm to a 40S&W or 357Sig

For best results converting to 9mm from 40 S&W use a 9mm mag.
