Pietta .45 Colt replica. Mine is the rival Uberti ... so it's possible they are different; mine has no transfer bar. The firing mechinism is a beak on the front face of the hammer. Haven't tested it for being drop safe and not inclined to do so: prefering the traditional way: empty chamber (actually a dummy / spent case) under the hammer. Haven't shot it for a l-o-n-g time; had to dig it out to confirm no transfer bar.Does anyone know the exact gun they were using?
