In regards to the 1851 navy, I took it apart to inspect it and alas, the trigger spring was broken, I do not have a screwdriver that woul turn the trigger spring screw, and as a result it's really buggered up! I'm kind of new to all of this ( as far as repairs) and would welcome some advice. Do these guns function well with aftermarket parts and is there anywhere to get better screws for these things? The ones in it seem kinda "soft" for lack of a better word

Invest in a good set of hollow ground gunsmith screw drivers.

They will make your life easier.

Where can I find this set of screwdrivers?

I bought a decent set at Walmart.
You might want to try some break-free spray or oil on that screw, and maybe a little heat.

Oh they can be found at Walmart? Outstanding, I've tried the breakfree etc. on that screw, I have yet to try heat. Thanks for the info, I hate leaving a project half finished! I see several places to get parts, does anyone have experience with the Good, bad and ugly of it all, or is one as good as the other?

Do you know who made the Hawes revolvers?

This set will get you by quite nicely until you become a professional gunsmith.

NOTE: PROFESSIONAL GUNSMITHS are hard core and make their own screwdrivers in their spare time during coffee breaks.

Then, after you have the right size tip to fit the slot?
Put it in the slot and whack it a couple of times with a light high speed hammer blow.

The shock will break the threads loose and it will come out like corn through a goose.

Better trigger/bolt springs that won't break again are available here but may require some fitting depending on the brand of gun you have.

OEM replacement springs for most brands that will break again are available here:

You can also Hollow Grind down screwdrivers that you buy second hand. That's what pawn shops, garage sales, flea markets, second hand stores are for.

Yes, but hollow-grinding a junk drawer screwdriver and hardening the blade without melting the handle is one of those life skills I still haven't mastered after 50+ years of trying occasionally.

If you simply have to work on guns?

Buy some decent gunsmith screwdrivers!!

Thanks for all the helpful info rcmodel. I'll definitely be getting a decent set of screwdrivers. Also, if I get the springs etc. that WON'T break what tools are best for "fitting" them?
Perhaps one day I'll make it to hardcore gunsmith status, but I have a long way to go.

Blank Stare, these PDFs ought to help you. They're written for a Pietta; but your Armi San Paolo/Hawes is put together the same way.

I seem to repeat this about every month but here is a way to handle stubborn screws if you have access to a drill press.

Chuck a stubby screwdriver bit into the drill chuck. Pad the part and clamp it into the drill press vise. Maneuver the chuck, vise and table until the driver fits into the screw slot. Lock the vise and table. Hold the chuck into the screw slot using the drill press handle. Using hand power only (do not turn on the drill press motor), turn the chuck, working it back and forth.

That will break loose even the most stubborn screw if it is going to break loose at all. If that doesn't work, use the drill press to drill out the screw.

P.S. It also works for stuck nipples, substituting a nipple wrench for the screwdriver bit.
