Hammer spur
« on: October 09, 2011, 10:39:43 AM »
Will H&R sell the hammer spur by itself?  Is there another source that is reasonable?  The local Walmart used to sell them but they said they no longer sell them.

Thanks,

Off the top of my head try Numrich (e-gunparts) or Brownells.  Don't remember which I got some from.  Goatwhiskers

The H&R hammer extension(not the spur which is part of the hammer) is made by Uncle Mike's part #2456-0 same as for a Ruger Black Hawk, lots of sources for it, see the scope bases section of FAQs and Help sticky.

I thought I read some posts about the weight of the hammer spur resulting in light primer strikes, enough to cause misfires.  What is the consensus on this?  Now that I've scoped my .45-70 a spur would be handy.

It might, specially with a weak hammer spring, that's why those of us that do our own trigger work replace the hammer spring with a Wolff extra power spring. I've also used much lighter hammer extensions, all are covered in the low profile hammer mods links in the FAQs.

I just took mine off and learned how to hook the hammer with the tip of my thumb, now its second nature and no worries gun to gun.

Dont remember where I had purchased my hammer extension from or who made it. I was quite a while back. I have never had any trouble with mis-fires or a weak hammer strike. I can tell you that it made things a whole lot easier once I installed it.

As soon as I installed the hammer extension on my 45-70 H&R, I started having a lot of problems with ignition.  About 1 out of 5 cartridges would fail to detonate on the first strike.  Of those, I had to hit them up to 4 times until they would go Bam!. 

The only positive thing about it, is that the failures to ignite demonstrated that I don't have a flinch problem.

I guess I should have mentioned that it was on a rimfire. I guess that would make a difference? ???

I believe that the FTF with one installed is because it changes the 'timing (inerta fall time)' of the hammer, letting the T-bar striker drop just enough to squirt out on strike from hammer from good, solid F-pin contact. A stronger spring help to counteract this, but is likely secondary to the real cause, but if it solves it, fine, its an easy 'fix'.
