Hello,

I have an H&R Sportsman (SN 45126) that I repaired. It arrived with a broken trigger and SA Sear. I have made it functional again, but am getting light strikes. It does not appear to be consistent with specific cylinders. I am wondering if the issue could be a missing part. The gun was purchased partly disassembled, and I have done my best to get it in working order. Based on my experience with the gun during the repair process and after doing some more research on the parts, I believe I am missing the guide seat for the mainspring. The Mainspring IS a metal head model, but there is no guide rod seat on it and the spring sits in it's own recess within the frame. I just assumed that this is how this iteration of the gun went together as I found an image of the same frame gun with the same setup. However, every other image/part I've seen of the mainspring/guide rod assembly comes with a guide seat.

My question is, does my issue lie with a main spring that is under compressed, or are there other potential issues I should look into?

The one diagram I found online for the 199 Sportsman doesn't show a guide seat for the main spring.
It does show two versions of hammers and firing pins. One with the firing pin mounted in the frame and the other with the pin as part of the hammer.
It could be possible that the firing pin is worn (I'm not an H&R guy but I've seen it plenty of times on Iver Johnson's). It's also possible that the mainspring is weak. The wrong firing pin spring on pin in frame models could bind up and not allow the pin to move forward enough. Last possibility is if you have the mainspring guide installed backwards where it meets the hammer.

It's a 999 model not a 199, though many things are similar. Mine is also not a Firing Pin type, it's a solid blade hammer. It's possible the hammer is worn down, or the mainspring is worn out. I do not know their age. I believe the mainspring/guide to be non original as I understand the early models all had plastic guide rod heads not metal. The orientation i believe is also correct, as I don't think it will even fit if you try and install the main spring upside down.

Show me a picture of the front of the hammer. Yes they wear down and even break.
@goofy

first image is of the hammer pressed forward inside the frame. Second is of the hammer by itself.

Thank you.
The hammer head protrudes more then enough to ignite the round.
Yes it it suppose to have the guide seat. After installing one try it if it still has light strikes try pulling the trigger and pull the hammer back as far as it will go and holding the trigger closed let go of the hammer if it fires when doing this then you need a new main spring.

Agree with Mike, plenty of firing pin there.
Taking a closer look at your pics, I can see the wear mark where the bolt locks in the cylinder, and it's to the rear of where it should be. Another good possibility, the cylinder has been replaced and not properly fitted, or worn to the point of excessive end shake. With end shake, when the hand comes forward and up to rotate the cylinder, the cylinder is pushed forward away from the firing pin.
With the gun un-cocked, grab the cylinder, and see if it moves back and forth.
Forgot to add, the guide seat adds tension to the hammer spring too.

I will check the cylinder again, but during my checkout of the gun I followed THIS REVOLVER CHECKOUT guide. When I was checking it out, I do not recall any front to back shake. When decocked there is only slight rotational shake, and no shake at all when the hammer and trigger are fully back. The cylinder gap at the front is also not undersized. However, I will check it again following your advice, as if the cylinder was moved forward, then it wouldn't matter how hard the hammer falls if the head can't fully reach the round.

I am thinking that the main issue is the Mainspring, as it's missing its "Preload spacer". It's possible that the mainspring is still in good condition, but the lack of a proper spacer means that it's not under enough tension when the hammer completes it's arc.

The other thing that I noticed when taking the photos for Goofy of the hammer, is the hammer screw moves with the hammer. I come from a Car/Motorcycle background, and things that are effectively "Axles" should not move with the thing they are suspending... at least unless they are supposed to. I DID use some loctite blue on the threads of the Hammer Screw, and either from the shocks from firing or from the simple hammer action, it has worked it's way free. Is this normal for this firearm? Or am I correct in my assumption that the Hammer Screw should not move once installed. If it shouldn't be moving then I have some cleaning and polishing to do to prevent the hammer from torquing the screw loose during use.

No, the hammer screw isn't suppose to move. Yes, it turning with the hammer would slow it way down. Remove both, and check the screw for galling. It should drop into the hole on the hammer.
