Gun screw impact screwdriver recommendations?

If you're using heat, you may not be using enough heat. I often stick parts that are frozen into the oven. Get the whole thing hot and then hit the frozen part with something cold, like a cube of ice.

If you have a drill press and the correct vises, you can use it manually to turn the screw with the bit in the chuck. Impact screwdrivers are kind of the last resort before drilling and due to close fitting of revolvers, I would not personally use on on it. Use the drill press trick first if you have tried all others. Be prepared to get a new screw in any case.

Last ditch involves drilling plus some other rather distasteful methods that can go South quickly if you are not careful or do not have the right tools. I would go to a gunsmith before doing that unless you are willing to risk a screwup.

Be careful when using the drill press. Even when turning the chuck by hand you can apply too much torque!

Heat, Kroil while still hot until cool (yes it will smoke until cool enough not too, but this is when Kroil is able to seep down into the threads), try to lossen.
Didn’t work?
Repeat Tomorrow (not today) and the next day and——-Sometimes it has taken a week (5-7 days), but this method has never failed me yet.
Patience is the key and a virtue!
And best of all the screw is still usable in the end!

Good luck

If the screw is frozen and needs to come out, the screw is basically toast at this point anyway. The close fitting nature of side plates of revolvers is why I would not use an impact device because if it slips, you can easily damage the side plate. The old trick of welding a projection would also be problematic as it could cause warping of the sideplate through transmission of heat.

Thus, the next step would be using a drilling out the screw and using various means to do so to allow extraction. You would need to use a drill press for that anyway.

Do you have access to a drill press? I have used one to pop a few really stuck screws and bolts before. The drill press is not to drill though, just to hold firm downward pressure so that the screw and/or screwdriver don’t deform and slip out. I have used a long adjustable wrench to turn bits, and I have used a pipe wrench to bite into soft screwdriver shafts and turn those after I cut the handle off. That last option is last ditch but it worked.

i need a good, small impact screwdriver for just here and there work on frozen gun screws. Currently I have a frozen
Side plate screw on a blued Taurus 85 that holds the cylinder in place. The revolver is mint, but I guess locktite was in use several years ago as just that one plate screw will not budge; the others came out fine. Minor Heat, soaking for hours with oil, Gunsmithing bits and screwdrivers have had zero effect and the slot is starting to deform a hair. Before it gets messed up I thought about a small impact driver to break it loose. Suggestions on one that will hold up to some occasional use please? Anything you have done to unlock that cylinder retention screw I haven’t tried yet would be greatly appreciated as well, thanks .

During install, the screw was likely over-torqued at the factory. I'd let Taurus fix their mistakes.
