I have the Accusport model of Bisley 45 Colt:
I use this beauty as a woods gun during hunting season. I had a chance to use it on a deer once, but the deer jumped out from in front of me and scared the $%^& out of me and I missed. It handles well and shoots great. It is not a convertible with two cylinders.
I do have a old model Vaquero that is a classic with two cylinders. I used them in Cowboy Action Shooting, but since have replace them with new model Vaqueros. I did keep one of the old model Vaq. It was a shooter and I had a soft spot for it.
