Waiting till somebody posted..I had one, tow Sundays ago..I am a fairly new 'returnee' to guns after a 25 year or so hiatus..Spent some time(20 years) in the military(USN aviation) and altho not in ground combat arms, I knew 'some' about rifles and handguns.
Uberti/Beretta Bird's Head/Thunderer in 38..up in mountains with 2 son's.
Reloading the revolver..pointed at ground, hammer back 1/2, gate open, reloading. Once full, gate closed and instead of just pulling the hammer back full, this time I pulled hammer all the way back, then squeezed the trigger to then 'carefully' let the hammer go forward, then cock it..Pointed at the ground, thumb came off hammer and bang..into the ground..but really dumb..
Next time, after loading it, either leave the hammer 1/2 or just cock it , THEN point it, THEN squeeze the trigger..
