I bought a couple of L579 in .308 last winter. One seems to from the 60s because it has a square tang on the floor plate while the other is rounded and likely made later? I like them both. I acquired a scope for the earlier model and like the set up but...when I took it to the range I took one shot and the trigger hung up on the trigger guard. I thought it looked close and it is. The safety is was also hard to move so I took it apart. I am not a mechanical person so that was tense but I managed. Now the trigger sets better and it seems to work. At least it works with snap caps. The safety still is very stiff and there seems to be an adjustment screw missing. The first photo shows the final trigger position. The second is the original position. The third shows that the is a screw missing that goes where the housing is diagonal. I know it is missing because my other gun has one. I plan to move it to this gun if it fits. Can you tell me if I have done a good thing by adjusting the trigger? Any ideas on how to smooth out the safety? It does work, just not smooth and easy. What is the function of the missing screw, how should I set it, where can I look for another? I am a fish out of water with this but it is kind of fun too. Please help me if you have ideas.
