Just got two of these in. On the older one found that the automatic intercepting sear will not press down when the barrel is closed. When I take the the little spring out of it it swivels very easily. I have tried various springs in it and it just will not move when the barrel is closed. Seems a simple fix but I just cannot fathom why it is jamming. Also I suppose the correct back sights that fit in the large dovetail are hard to find for these ?
