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,
