Broke the firing pin in my Model 50 ( ??????? )

[19Steve67]

Afternoon Fellow Reising Owners:

   The firing pin broke in my Reising Model 50

recently and I have replaced the firing pin. My

question is can the broken firing pin be repaired?

I realize this question may show my ignorance 

but I had to ask those that know more than I. Also,

the person I bought this Reising from had a box of

spare parts included in the deal and there are ( 2 )

other firing pins that I NOW KNOW are broken.

Appreciate any reply.

You can shorten a firing pin and it will not break again.   I have not broke one for many rounds, before I found a fix I broke one about every 800 to 1 K rounds.

1. Broken Firing Pins

 

Broken firing pins are probably the most commonly encountered issue with Reisings. PaulF on this board posted an excellent "How To" regarding a solution to this problem. The post may be found at the following link:

Keystone Arms in PA has titanium replacement firing pins. 

I still alter them as described in the link above.

I would venture to say that PaulF saved us a lot of misery with his suggestion for the fix.

[Outsider]

Yep. one of the first things I did when I got my Reising. That and buy a spare just in case.

[19Steve67]

Thank ALL of you for replying to may post.

I will try the PaulF solution.

I will post my results.

BUT FIRST,  I have to locate a couple of firing pins.

Call Keystone and speak to Crystal.  get one for use and two extra's

Tell her I sent you and she knows me as the guy that sent her a candy bar in a return.

I have the length I shortened mine down to in .000 if I can find it I will send it to you.    I shot the heck out of it today cleaning snapping turtles out of my son n laws pond and the pin is reliable as can be so far anyway.    I might add, I keep the cavity the pin rides in clean as can be so it will be free to move as a inertia pin.   I dunno if that makes a difference but I feel better just the same.

   Thank you for your offer 

and I will definitely try on 

my remaining firing pin.

In terms of preventing breakage I think that may actually be more important than converting the firing pin to inertial

OK. Direct answer to OP's original question.

Yes, broken Reising firing pin can be repaired(maybe).

Depends on exactly where it broke. If just small amount of the tip then it is possible to repoint by welding and reshaping. Other method is to cut off damaged portion, dress, drill a small hole for replacement tip made of round stock. Insert replacement in hole and soft solder, silver solder or braze. High temp of brazing or silver solder can cause pin to warp, be careful. Then trim to length.

Had pretty good luck repointing that way although I replaced repaired pin ASAP. Will see if I can find it in the box o" parts.

Had a pin break just a tiny amount once, maybe a 1/8". 
Dressed it down and repointed. Put a lighter Firing Pin Spring in it. The gun worked ! Did not get any primer dimples from chambering. Would not recommend this though, could lead to slam fire if not done right or not work at all.

Yes, the FP modification is good idea. The Reising had a lot of hand fitted parts, one of the issues that kept it from being a good Military weapon.

Best to buy and fit a few spare FPs for the gun, along with an extractor and screw. I keep a spare set in a hole under the buttplate of mine.

Might be, common sense says the pin needs have some movement it is important to not have any gunk in there to put some drag on the pin.    As dirty as my gun runs it makes sense to keep  it clean.   If I put light oil in there dirt would stick to the pin and channel.   I use dry moly in that area,  slick stuff and does not collect any crud  compared to light oil of some sort.

I appreciate ALL of you that replied to my post.

My pin is titanium from Keystone with a wolf spring.   I have it down to 3.970.    Once in a great while I will get a lite strike, no big deal I'm just playing around anyway.    If I ever do a pin again I will add a few thousands.     I have put about 2K rounds thru on this pin and it is still going strong.

I was getting a few light strikes as well from my shortened titanium pin. I ground a couple of thousands out of the front of the retaining pin slot so that the end of the pin protruded out of the back of the bolt a little further, solved the problem.

PaulF inertia firing pin mod is awesome. I did and no malfunctions. 

 

I did have to file the Grove a bit to allow my firing pin to protrude more forward to allow solid contact to the primer.

Ryo,

Are you referring to the groove in the firing pin ?

[Frank I.]

yes

[fartsalot]

I thought so but wanted to be sure before I started grinding away LOL.    Ever once in a while I get a light primer strike, it is seldom but easy to solve.

Thanks

[StrangeRanger]

Be careful to maintain the line of the bottom surface of the slot, deepening it significantly could cause problems
