I want to start hunting with a handgun but can'd decide on what action. I love single action but I don't know if the noise of drawing back the hammer will spook game. Why did you pick the revolver your using?
I've been using revolvers for deer hunting since '79 and iron sights all the while.
I have and use both the single action and double action. Regardless which is used, I fire them using single action.
I cannot claim one is
better than the other.
The double actions have a faster lock-time, (that brief period of time that begins when the trigger releases the hammer and when the gun actually goes Bang!)
The difference can be significant and is why many shooters become more accomplished with a double action revolver.
Fast lock-time is always a good thing for all shooting.
For hunting purposes that is about all the difference there is to consider other than price.
I have not yet fired a handgun upon a deer that was farther than about 42 steps and usually they are under 30 steps and recently 20 steps or less is not unusual.
In all these situations I have only seen one deer acknowledge having heard the cocking of the single action I was using. The deer's reaction was to look hard at me as if trying to understand what it heard and saw. This deer was 19 steps distant and his rack is on my shop wall.
I think the idea of "spooking" game with the sound of cocking the gun is laughable if that game is as far as 25 steps.
When they're closer than that you have to think carefully about everything, including how to muffle the cocking sound.
Get the one you like and shoot it enough to become a good shot.
That will matter much more than the noise of cocking.
You'll see.
