Martini Triggers

[Martini2]

Hope some one may have input. I have a Martini target rifle built in the '70s by Navy Arms. It is a Greener action in 45-70, barrel is full Qct. 30 inch. Rifle is accurate albeit the single trigger pull is monstrous. Very heavy but breaks clean. It takes quite a bit of concentration to make good shots, good as in sub minute groups at 200 yards. Does anyone know of parts or techniques to improve (lessen the trigger pull). This Ol' gun is a lot of fun I.E. today friends and I gathered at local club that has hanging gongs at 200 yds. From a bench the Martini was painting the 6 inch diameter one very readily. As might be expected getting off hand shots off is not so good. Thanks

I don't know if the large Greener actions are close to being the same as the smaller cadet actions but I picture them as being pretty close on the insides. I would think that any good smith that can do hand gun trigger jobs such as a 1911 should be able to smooth and crisp up your trigger without too much trouble. Some of the Cadet actions have some very nice crisp triggers on them.

According to drawings (and examination of parts) there exists a one piece link between firing pin spring and the sear. Thus all the spring pressure bares on the critical trigger sear. The part's geometry actually presses advantage of spring force over short section that is sear arm. I've searched the BSAs and target versions of Martinis and to be sure gunsmiths can lesson the sear engagement and lighten the firing pin spring. I hesitate to get aggressive with those techniques because of obvious safety implications. I was hoping some experienced guide might suggest "easy fix". We know how random and rare such things can be There does also exist on this big Greener one adjustable piece (save reworking parts).
That is the treaded backup part that holds the firing pin spring in block. However the threading is so course one turn in or out is all that's possible before the function of lever and block is out of time. Must be the redundancy built into this Ol' action. One thing it does albeit with stiff trigger pull is keep on booming. Thanks for comment RJB
