If you know your way around a single-action, then you'll know how to cock it very quietly, or nearly instantaneously with firing (have you ever seen the videos of the guy who is the fastest shooter in modern times, who can fire a single-action revolver 5 times per second?). Even I am only slightly acquainted with revolvers, but can do both of those things (I'm also a girl

). I just experimented on a single-action .44 and I could probably sneak up on someone before they hit me with a shovel.
In my mind a misfire followed by the MC being so shocked that he looks down at the gun kind of stupidly gives him time to be knocked out by a shovel, more than the first scenario.
If you would like a really funny visual, I was in a shooting competition once, and using an automatic that kept misfiring, kept "stovepiping" the spent casings, which means that basically they were getting stuck halfway out instead of being completely ejected. I was wearing a hooded jacket (hood down), t-shirt, and blue jeans. I was very embarrassed because it is very difficult to be in front of a crowd, under pressure of a timed event, and your equipment not working at all. Several men were standing around behind me trying to help me out (informal contest). It
finally ejected a casing properly & the d@mn thing went up in the air & got caught by my jacket, I guess. A scorching hot casing went down the back of my shirt. With my husband & about 20 people standing around, some of whom were ex-military, I started to dance a little jig, freaking out because I could feel that thing burning me everywhere it touched me. In my hand I was holding a fully-loaded .40 S&W automatic pistol. That I had forgotten I was holding. After accidentally pointing it at about 5 people while I did my little jig, my husband managed to safely disarm me, saying, "what on earth are you doing?" About a second later I jiggled my right leg just right, and a casing came out of the bottom of my pants leg & clinked across the cement floor, loudly clinking because everyone was quiet, watching me in amazement. What followed next was riotous laughing and nearly 5 minutes before the shooting competition could continue. Then a lecture about putting down the gun
before attempting to remove hot casing from pants.
Totally unrelated, but my funny experience with a misfire, and then a crazy casing. I do know that if your gun misfires, especially if you are very tense (such as sneaking up on someone) the first thing you do is be a little surprised & then look down at your gun, LOL.
