Mod 36 mid 70's hammer won't hold SA lock

[Nicksterdemus]

Am I more than likely looking at replacing the hammer and sear?

Can you ballpark me on a rough cost?

My brother is looking to buy and the seller seems to want an offer as opposed to asking a price.

I'm guessing leave as is for DAO, maybe bob the hammer or restore back to original condition depending on the cost.

Am I correct in assuming that there's a safety block of some type to keep this firearm from igniting a round under the firing pin?

Could the hammer have taken a blow causing it not to hold the SA lock and disabled this safety at the same time?

Any thoughts would be appreciated.

Thanks

Hammer spur is bent, per photos on your other post. Either bob hammer or replace it.

Thank you sir. That should be easy/cheap enough. Seeing how it's already bent I guess I could bob this and see how I like that configuration.

I guess if I lightened the hammer I'd want a new mainspring possibly of higher lbs rating.

I'll pass the information on to my brother.

Why? Are you having ignition problems now?

 

[Nicksterdemus]

Not to my knowledge. I've never seen the gun in person. I was speculating that w/reduced weight of the hammer and the gun being a '75 model that it might need a new mainspring and possibly one w/heavier rating.

I was talking out loud I guess. To my knowledge the gun fires in DA.

Bobbing a hammer does NOT cause light strikes or necessitate a heavier mainspring. If it is igniting primers now in DA, it still will with the hammer bobbed. Might even do better, since lightening the hammer speeds it up a little.

"Could the hammer have taken a blow...?" Yes. If the bent hammer spur keeps the hammer from coming back far enough for the hammer hook to catch the trigger ledge, it would not cock, but as to a "safety," unless you are talking about the hammer block, I don't understand the question. The hammer block moves down, out of the way of the hammer, when the trigger is pulled, so the hammer nose can strike the primer. The blow to the hammer spur would not affect that.

 

[Nicksterdemus]

Wonderful! I never knew the ignition might improve w/less weight.

"The blow to the hammer spur would not affect that."

That's what I wanted to know I just didn't quite know how to ask the question.

I didn't want that brother to drop a firearm and shoot himself.

Thanks for helping.

Happy to help. The hammer block prevents just that, i.e., any chance of a blow to the hammer being transmitted to a primer, unless the trigger is pulled.

Offer $200 if the rest of the gun is real nice.
