Top break latch adjustment?

[Mbrgr1]

Hello all, I have been trying to remove the latch screw on my new model 3, Kroil. PB blaster, heat, etc etc.


I'll eventually get it, but I am wondering if (like some other manufacturers) S&W used that screw to make fine adjustments to tighten or loosen the latch??


Thanks.

Frozen

The screw is not for adjustment but they are often found frozen solid!

Not an adjustment screw, but if you still need to get it loose here is a method that a lot of us have used with good results The best thing you can do is drop it (remove the grips first) in a metal container of a mixture of one part acetone one part automatic transmission fluid sealed with a lid for a few days then try it. Do not use this mixture inside yiur house....You won't find these screws at any hardware store...

I recommend soaking the barrel/latch in a 50/50 Acetone/ATF (AKA Ed's Red) for several days in a sealed metal paint can.. for a week if you are patient. It WILL come out using a properly fitting screwdriver.

Thanks, will try that combo! So the only way to tighten the latch to the frame is to have the tangs adjusted outward? Bent for lack of a better term.


Something my overworked and dreadfully behind gunsmith can do I'm sure.

The "tangs" can't be adjusted the latch engages the notches at the rear. If it is loose something is worn, or the latch spring is missing, broke, or gummed up. Perhaps a more detailed description with pictures would help.

Thanks, I'm talking about the frame where the latch connects, the spring is fine and it locks up, just a little play when latched.


That's why I asked, on some of my other top breaks, turning the latch screw and it being slightly out of round effectively pulls the latch forward making the lockup tighter.

Smith & Wessons have no such adjustment the screw is a straight through screw all it does is hold the latch, and offer a pivot point for said latch.

Uneven wear

Not uncommon for a wear pattern to develop on antique screws or for them to actually bend from load. Especially hammer screws.
Not a lot of load on that screw but if you turn the screw to correct the problem? It’s only a very temporary fix since the screw is now loose and will again eventually work it’s way back to that worn area.

Hello Mr. gr1, are you planning on carrying this gun for self defense?
or just a backyard shooter? Just let the old girl retire after 130 years of service.

This old girl has been neglected for a long time, so I decided to at least get her in working order.


From the time I picked this up in the Walmart parking lot, I have cleaned and adjusted, uncovered hidden serial numbers, replaced the hammer stud and screw, freed up the mainspring screw, discovered it was probably nickel originally and a 4" barrel. I have two original hammers coming from a new friend here on the forum to possibly correct the freewheeling issue and am waiting on a factory letter!


Self defense?? No! Self Respect!, my good man!


Think of her as Gloria Swanson in Sunset Boulevard and I am William Holden, I'll probably end up face down in the pool!
