I need a wedge screw for a 2nd gen F series 1851 navy.

Every place I googled says they have them for replicas, but that might be metric.

One place said they had them for originals, but they didn't think they fit 2nd gens.


Any "go to" places that can narrow it down for me?

They don't have to hold very much strength wise, why not just re-tap the hole for what ever larger screw you can get barring the ability to just make a new one of proper size and thread pitch !

If I had the equipment, and knowledge I would.

Have you tried Dixie Gun Works ?

Any good machinist you might know or local gunsmith should be able to make you a screw with ease but it probably will be a least 25 dollars or so. It seems like a lot but it will take them at least an hour of their time to turn, thread, slot and blue it for you.
That amount will quickly be eaten up by a couple of mis- fitting screw package and mailings !

my bet would be 8-32 threads, any good machinist shop or gunsmith could tell you in a few minutes

You have to be careful in replacing screws in 2nd and 3rd gen Colt percussion pistols. They are American thread, just like the originals. The Italian repro's use metric thread screws.
If you still have the original screw, simply take it to a local hardware store. They will have a gauge to measure the size and thread of the wedge screw. If you don't have it, simply take the wedge screw of any other 2nd or 3rd generation pistol and measure it.
You might consider purchasing a set of thread gauges and screw diameter gauges. They are really handy and not that expensive! These gauges are the "forgotten tools" of most tool boxes. Old Arms of Idaho supposedly sells a vintage repo of original

I just bought a replacement Uberti 1851/1860 wedge screw, and I'm pretty sure it's #8-32 thread, not metric. Would it help at all if I confirmed the thread size for you?

Some metric screws are VERY close to some SAE standard size screws so it is best to have something to measure the screw or threaded hole in your case. Threaded holes are measured with threaded plug gauges or a known screw that fits the threaded hole. Threaded plug gauges are expensive so your best bet is to go to a GOOD hardware store that has a selection of both metric and SAE machine screws and try and find one that will fit. Good luck --

After extensive reading and rabbit hole exploration on the internet.

I found a post where a guy said the screw from his 2nd gen fit perfect in an original. So I bought a screw for an original colt. If that don't work I'm taking my barrel to the hardware and trying some on.

Thanks for all the help.

If it doesn’t work let us know, I have a second gen 1851 colt navy and I will take my screw out and measure it.
