H & R 929 light strikes

[351 WINCHESTER]

I picked up a 929 and have about one light strike out of 9. Happened twice. All rounds were fully seated and gun was lubed. Cylinder had very little endshake.

I took the grips off to see if it had an adjustment and darned if I can see one. Looks like I may need another spring - Gunparts?

Have had that same problem with mine a few times. Check with Numrich aka GunParts by any other name for parts. You can get a schematic and parts list from them on-line. Here's a good link.

The pawl on the main spring guide assembly is very likely your culprit. There are two types; a nylon variation,..which breaks pretty easily,..and a metal version that tends to last a bit longer and works better. Remove your grips, remove the main spring guide assembly...... Almost willing to bet that your spring is fine,..but that pawl linking to the hammer is broken off. If that's not the issue,...your guess would be as good as anything else. Good luck.

I have had a light strike problem, a lot of it is ammo related as in different thickness on the case rim, plus if it has had a lot of shorts shot through it you may need to get the 0000 and Kroil out along with a drill and polish the chambers, I went as far to chamfer the chamber mouths with my case deburr tool, not very much.

Does your misfire fire on the 2nd go roumd? If it does it IS a seating or case rim thickness problem.

One out of 9 sounds like it might be a problem chamber.

Have you checked to make sure it's not always the same one?

I thought about one chamber being the problem and will further investigate the problem with different ammo and by marking the "offending" chamber if found. I made sure all rounds were fully seated. Thanks for everyones input.

The gun does have one offending chamber. How can I fix it?

I already tried the normal things - cleaning the cylinders and under the extractor. Funny thing is when I insert and fire a spent round the firing pin indent looks fine. I can not tell any difference by feel or visual inspection that would indicate a problem. I'm beginning to think it may be related to the thickness of the rim. I will try different ammo and see if that helps.

Depends on the problem.

Are the chambers countersunk? If so, make sure there is no crud that could cushion the firing pin impact. Also check the countersink depth; if the bad one is a bit too deep the pin will not be hitting the rim as hard as the others.

Is the pin strike in the same spot on all the cases? The bad chamber might have been bored slightly off-center and the pin is missing the primer compound.
