209x50 Encore pistol barrels.........

I know this has probably been discussed at length but I am considering having a 209x50 Encore pistol barrel built. I was wondering if anyone here had any experience with either T/C or MGM ML barrels? What velocities did you get? Any pictures of MGM 209x50 pistol barrels? What type of breech plug does MGM use in their barrels?

I'm not sure about that, but everyone who has switched to this has had nothing but good to say about it:
ACP
If they had one for my Knight pistol I'd own it.
