Adjusting screws Uberti target 1858

[HisSoldier]

I got my target revolver and right off noticed it was shooting 6" high. I know there is some philosophical differences about aiming points but I've always wanted the top of the front sight to be exactly where the bullet hits, not 6" above that. The pattern was about 2" left at 35' also.
When I went to adjust the sights I found that they were tightened (I thought at the time) way too tight, In later discovered they had applied a thread locking fluid..
Of course I buggered the slots but even worse the threads were damaged. What's the point of having adjustable sights if you can't adjust them?
Anyway, after surface grinding the bottom rear of the sight and putting a slight bow down on it, plus milling .020" off the bottom of the rear blade and dovetail I'll accept what I have when done, though I expect it to still shoot slightly high.
I'm happy now except as I said the threads of the adjusting screws were damaged, and neither M2.5 X .4 nor M 3 X .5 will fit. It may be one of those but I'm afraid to force it.
To head off sniping about what screwdrivers I was using gunsmith drivers, and even so one of them snapped the blade off.

So, my question; These are very small screws and it's hard to see if they conform to a screw pitch gage even with a 20 power loupe, but could one of you check the pitch and diameter of the adjusting screws from yours? That is if they turn easily, I'd hate to learn that someone else messed up theirs.
The threads are quite a bit finer than an inch series 4-40. It's possible they used imperial, but either way there isn't enough room to retap the threads out farther. The best I could tell with the loupe was .05 MM pitch. Gosh I hope the diameter isn't some proprietary size.
Thanks,

I did email Uberti USA 0ffering to buy replacements but I haven't heard back from them in three weeks.

You might try VTI gun parts.

You might try VTI gun parts.

They have the screws for 4.45 each and a complete sight is 47.00.

Thank you very much Woodnbow! At the very least I'll have a sample of the thread size to make my own, why? Because, (Firesuit on) I think I
I'd rather have hex socket screws than slotted. Or maybe not.

Well, either way works!

This post makes me hesitant to ever buy anything from uberti. I would expect their fancy target model to work well and not have any of these issues.

I don''t own one but thanks for the heads up. I had no idea they gorilla torqued/glued sight screws as well. I looks like these may require a torch to heat things up first.

I’ve never owned a target model but I couldn’t be happier with the others I’ve owned... Pietta is good too but they miss the boat completely in some admittedly cosmetic areas so I’ve stuck with Uberti. Your mileages may vary.

Thanks,

cant you go to Taylor and co. or Dixie gunworks and order the exact screws for that revolver there are several places that sell replacement parts for uberti and pietta revolvers they are not interchangeable to my knowledge

I did order the screws from VTI. It appears they are stainless rather than the original blued screws, that's getting down below the couldn't care less level for me as they are so small.
I didn't mean to bash Uberti as the gun is very nicely fit and finished, though I did make my own grips as the originals had wood/metal gaps on both sides. My advice, if one can do it, is go and look at the actual guns at the store and really examine them before purchasing.
By the way, I see now that the front sight on the Uberti Target Model is set in a very small longitudinal dovetail that is at the top of the sight base, it would probably not be too hard to drive it forward out of the dovetail and make a new taller sight blade, to lower the impact area.

i had pretty much the same problem with a traditions stainless steel 1858 target iout of the box it shot a mile off and when i tried to adjust the rear sight i lost a spring from behind the screw so i ordered another spring within a week of taking the gun out of the box and replaced the spring sold the gun because it wouldnt adjust to hit where i wanted it too for the life of me and have stuck with fixed sight and just figuring where to aim to hit the bullseye..
