386NG titanium & Tritium 30.jpg
I wanted to modify mine, too.
I substituted the titanium cylinder and had C&S put tritium tubes in their Extreme Duty sight.
Since I can and do carry it in a pocket holster from time to time, I wanted the lighter cylinder.
C&S opened up the rear sight a bit to accommodate the Big Dot. Works great. They sighted it in with the Cor Bon ammo.

It's has been a frequent companion, and a couple of my friends like to carry it, so it isn't home a lot.
