You need a generic gunsmith set since no two Italian clones have the exact same slot widths anyway. So I'm not sure if that "Colt SA" set would work or not.
I sort of wish that the tips came in bulk packs of 10 in different thicknesses and a couple of different widths. Then I could select them for thickness and dress down the width to match the screws in a particular gun. At that point I'd set that set of tips aside in a container for that gun.
2nd that from the other pards.
The tenderfoot I was at one time used regular civie tools. The screws were so tight on some of the Eyetie guns I would bugger up the screws.
Not really. I've got three different 1860's and while the screw heads are all the same diameter the slot widths vary by a blade thickness for each brand and period. The ONLY constant is that you'll need different tip sizes for every gun maker.
Which is why I'd like to be able to buy the tips in bulk so I can dress a few down for width and thickness to make a couple of in between sizes for each standard size.
In fact a shop project is to make up a screwdriver tip grinder that uses a 3/8 or 1/2 inch round diamond air grinder point with a jig for doing just this.
By the way, just because "Tiny" that works in the assembly shops over in Italy tightened up things so much that they are almost welded together don't think that YOU need to tighten them that far. It's surprising how little torque is needed to hold the screws in your guns in place. In most cases a weak wristed to moderate "pinch" is more than enough. And the screw threads and slots will last MUCH longer if you learn this fact sooner instead of later.
The proper torque for many of the smaller screw sizes is only a very few inch pounds. A typical #6 short screw torque is around 3 to 4 inch-lbs. And that is a VERY weak wristed pinch on a screwdriver handle. it is easily achieved by any adult with just a thumb and forefinger on the screwdriver.
Don't go for the Wheeler umpteen million piece set there are a lot of the bits that work but a lot more that don't work.
I should have trusted the phrase you get what you pay for and bought the Brownell's starter set and their grind stone for shaping the hollow ground bits then shaped a set for each revolver (Pietta Colt repro's).
When in doubt, grind your own.
Learned that from a genuine gunsmith.
He kept a lot of ordinary screwdrivers on hand and adjusted the tips as needed on his trusty grinding wheel.
So, that got added to my repertoire of in-field repair techniques.
