I am used to DAO. My department, back in the 60-70s issued wheelguns, Model 15s, that were castrated to DAO.. I spent nearly 15 years, 1971-1987carrying one. Even my privately owned pistols were converted to DAO. I became used to it. Nowadays a long trigger pull is normal. You set trigger by it’s its initial,then a secondary pull let’s its off…My concern is the spot in which the trigger lets off!! My 5904, carries for 3 years in LE, had a long letoff…in a shootout, no less. The reset put me off…got the suspect but a few moments of stored for me…a LOT of stress…
