I have what I want. Got 2 of the 2 1/2" barreled 325s. Ine has a titanium cylinder, the other I am going to replace the cylindeer with a 44 mag cylinder reamed to 45 colt and cut for full moons so it will fire 45 colts or 45 acps. I will have to trim the forcing cone portion of the barrel a bit to clearance the longer cylinder and recut the forcing cone, but I have that tooling. In 44s I have a dehorned 396, a 296 and a 696.
But, being a 45 colt fan, my choice in the poll would be a 45 colt.
