Restrictions:
Threaded barrels are Prohibited in the following states: Colorado, Connecticut, Delaware, Illinois, New York, Washington.
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.
