4006 marks

[wfblack]

My 4006 has a P stamped on the bolt lug. Does S&W proof their barrels? It also has a T stamped on the but next to the mag well. Also here's the heresy, does anyone make a .357 sig barrel that would fit these guns?

Welcome to the Forum!

I'm not aware of anyone who produces a commercial 357sig barrel for these pistols, however if you source a barrel for a 59XXTSW you can ream the chamber to 357sig but you must also change the barrel cam lug angles to match those of the non-TSW pistols.

A tedious job.
