H&R 732 revolver help

kidthatsirish

Folks I am replacing a bad mainspring stem on a H&R 732. I noticed that the firing spring striker (part #10 in the link picture) was not actually in this gun. From what I understand the pistol did function without it. There is a Pin protruding from the side of the lifter (part 21) for it to pivot on but the part is simply not there...I am assuming the hammer was just striking the back of the firing pin perhaps?

Any info on how this would affect the reliability of the pistol as well as other things like trigger pull, smoothness, etc. would be appreciate.

A little more information on the revolver would be helpful for an answer to your question. Good starting point would be to provide the letter prefix in the serial number to determine the year of manufacture.

Looking at the schematic it shows some take the fp striker and some do not. The fp striker is a safety feature that does not allow the gun to fire unless the trigger is pulled, which all modern revolvers now have. This requires the striker to rise up between the hammer and the firing pin to make contact. Just look at the space between the rear of the cylinder and the frame and pull the trigger. If the firing pin protrudes from the frame the hammer is hitting it and that is correct, no striker required, i.e., it was made that way. If the firing pin does not protrude then the striker and spring is required. The face of the hammer is flat for the old style direct hit hammer. For the striker model the face of the hammer is cut-out for the striker to rise up between it and the firing pin. The parts list shows the two types.

Hello!
It is apparent that someone switched out hammers on your revolver. Instead of replacing the firing pin striker, they installed a hammer that did not require a firing pin striker. If this was the original hammer, the revolver would not fire without the firing pin striker. It is dangerous for the revolver to be in this condition. You must ensure that the firing pin is always over an empty chamber. The firing pin striker is a safety feature that precludes the hammer from contacting the firing pin unless the hammer is cocked.
Check to see if the top of your hammer is configured like the one in the picture. I'm willing to bet that it is not.

I think the trigger needs to be held back while the hammer arcs forward to fire. If the trigger is allowed to move forward the fps will drop and the gun will not fire.

H&R's were considered the best of the cheapies, and might be worth fixing. I had 4" 9 shot that required pulling the cylinder and using the pin to punch out the empties. Was a really good shooter, but slow on the reload.

added The first holster I ever made was for a 8 3/8 barrel model 25-5 S&W in 45 Colt. On the first outing, when I got out of the truck my buddy ask me if I carried the pistol cocked? Apparently the process of sitting down or getting up and out had cocked the hammer. I added a safety strap to the hammer. My current design is a fully lined flapped holster. It protects the pistol and me.

Yes, the trigger is always pulled back when firing!! When the trigger is allowed to come forward, the firing pin striker will drop. If it didn't drop, it wouldn't be doing its job.
