Hi All, had the 39A out yesterday, I have not shot it much since I got it but I am getting a FTF 1 in 10 shots.

Pull the trigger and Click. Pull the hammer back again and Bang.

Not tired any other ammo in it, im using Winchester 22LR.

Its got a rebound hammer.

I went around the rebound hammer by replacing it with an older hammer, and trigger. The cross bolt safety dos nothing now, so I need to make a plug for that, like the ones used on the 1894's, and 336's.

If you remove the stock, you will see the strut. It is mounted to the hammer, and has the spring around the back part of it. It has two finger, so to speak, the bottom on hits the Hammer on the tree bound. That is what they are talking about.

You can grind the lower leg off the strut but you may need to go to a reduced power main spring as it may have to much force on the hammer. Also you will lose the half-cock on your rifle. The half-cock will still be there but if you pull the trigger it will release the hammer from that position and may fire the round. It is recommended that you use the safety after modifying the strut. None of mine will fire from the half-cock position but I have the reduced power springs in mine. The possibility is still there for a ACD it hits the rim hard enough from half-cock. The reduced spring also makes the lever work with less effort and the trigger lighter. J&P is the best spring from what the guys on RimFire Central say.

With a little bit of time and patience you can deepen the halfcock notch to work. I considered doing this to my 39a quite a while back.

Most often if you just stone a little off the lower area on the firing pin it increases the dent to the rim area, no other mods are then necessary.

About 5 years ago I purchased a 39A with rebound hammer. It maybe fired 2 out of 5 rounds. I purchased 2 rebound hammer struts and cut the offending lug (lower) and the 39A fired every time. I wished to restore the rebound action, so I took second strut and filed the rounded ball end of the rebound tang. In my gun I needed to shorten that part of the strut by .035". It required insertion and removal and measurement of the strut many times to arrive at dimension. Now my 39A fires every time with the Rebound Hammer active. Modify your arms with patient and deliberate with your own mods or let a qualified gun smith do it for you.
Happy plinking with some of the best lever actions ever built. I have 3.

I had issues with the rebounding hammer too. I bought a spare hammer strut on ebay and modified it in accordance to the info on the web. The result was that it acts like a pre-rebound rifle now and I have never had a FTF since. As mentioned, the CBS is now useless so I removed it.

Here is my thread on that:

I am very happy with my mods, but can easily put it back to factory AS confguration by reinserting the CBS and Hammer strut.
