DAO+Hammerless
I have a b/s S/W Mod 36 my father carried on the job and Stainless Mod 60 that I carried. Both were neutered as a department policy, even for off duty back in the day when we could only carry revolvers. In any case, I have both pistols, still carry them (although I wish one was the lighter 642) as an alternative to my SIG 220 .45 and both still have the hammer even though they will fire only in DAO. I may sell the Mod 60 and purchase a 642 and a keep the model 36 (fathers back up gun). Alternatively, I could have a smith take the spur off the hammer of the Mod 60 but that seems like a waste of money.
Bottom line, never present your pistol unless you intend to do something with it. Cocking it defies logic for CCW. ANd, if you present your pistol to someone in a "situation", you better be the first to call the Police and file a report before he does, even if he flees. Someone will report you as a Man with a Gun, better to be that guy first who calls the Police.
Just keep it concealed, non presented if you can help it otherwise, all the other drama mentioned in previous responses will come down on you. Good luck and be hammerless/DAO.
