What safety risk would that be??
My "silly reason" would be for a more precise aimed shot. I'm sure others are better than I am at DA shooting, and constantly shoot DA. I don't. I do shoot DA some, but I shoot SA a lot more and with a lot of guns. I'm just more accurate that way.
This doesn't mean I'm going to shoot a DA gun SA in an emergency situation. When I want the most precise shot I can make, and its NOT a self defense situation, and that DA bellygun is what I'm carrying, I want to be able to use it SA, if that's what I choose to do. And even a bobbed hammer gun can be used that way, if the SA function is not removed.
You say "might as well take it out, its not needed" and I say, "might as well leave it alone, it doesn't hurt anything".
So, we disagree. On that.
How are you planning on getting the hammer up to where you can reach/catch it?
The only way I know is to "pull the trigger", and that often results in the hammer falling unintentionally when you misjudge. And that's happening when youre not under any stress. Hows it going to work under stress, when your focus is on the threat and not the gun? But if you think youve got it covered, Ill take your word for it. I wouldnt do it, but then again, I dont see the point in doing it.
A "precise shot" doesnt come from the trigger, it comes from the sights. Youre sight alignment and where it is on the target is what gives you a hit on target when youre focused on doing that. My focus is on the sights, not what the trigger is doing, and I really dont even thnk about the trigger when I shoot. At least not consciously.
Once you learn to put your focus on the sights, things tend to tighten right up. If youre holding the alignment as you stroke the trigger, the rounds go where the sight are when the trigger breaks. Best of both worlds too, "somewhat" surprise break with sights aligned. The sights and the alignment dont move when the trigger is stroked either.
If I try to shoot for groups, my DA groups are almost always tighter than my SA groups. The reason is, my focus is on keeping the sights aligned, and I dont know when the shot will break. There is no anticipation of the gun going off, and no urge to force the shot.
With single action, especially with a light trigger, there is that tendency to want to shift your focus to the trigger and force the shot.
I think if you take the time to learn to shoot DAO, you will see an improvement in all your shooting, across the board, and with any gun you shoot. From what Ive seen and heard over the years, and I was there at one time myself too, the push back on doing that, comes from the SA shooters who dont believe its possible, and thats simply because they have convinced themselves they cant possibly shoot well in DA, and mainly because they never really tried.
Push yourself here, and I guarantee it will pay off. Or dont, your choice.
One thing about shooting is, there is never an end to learning and you never "get there". The only thing holding you back, is you.
