I've recently purchased a CZ75B SA 9mm. I wanted a regular DA/SA 75b, but CZ pistols are hard to come by up here in Nodak land and this one was on clearance at the local sporting goods store. It was too good a deal to pass up. Anyhow, I've been lurking on another CZ forum and I've gathered that some people convert their DA/SA pistols to single action by swapping out the trigger from a SA for a better trigger pull. I posed the question, is the reverse possible? Can I add a double action trigger pull to my 75bSA by swapping the straight plastic trigger for a standard metal curved one? If not what else would be involved? I haven't received a response from the fellows on the CZ forum so I seek enlightenment from the resident THR CZ gurus.
