    CPS action question

    My buddy purchased a CPS action rifle, it is 6ppc. We had a local match and the jewel trigger locked up and we shared my rifle so he could finish the match. When I got home he had a new jewel trigger that he brought over to change out failed trigger.
    Never having seen one of these actions, when I took off the trigger guard there was no trigger hanger, thatís when I understood what the 2 holes on each side of the stock were the pins holding the trigger in place. I knocked out the pins changed out the trigger and everything worked. However the new trigger seemed to me to be a little loose (wobbly) and I will add I had a new set of pins I used.
    My question, Is this normal or is there a way to tighten up the looseness of the trigger? Possibly an older action that the action holes are worn, and the action needs to be pulled and holes filled and re-drilled to smaller diameter?
    I took the old jewel trigger apart, and found nothing wrong except it needed to be cleaned.

    Was the old trigger wobbly? I'm not a gunsmith by any means but if the first trigger fit tightly and the second trigger was wobbly it would seem to me that you could just put it back like it was...given the problem trigger is now fixed.

    Wilbur, yes the first trigger was wobbly also, I initially thought that it being wobbly may have caused the first trigger to lock up. I was hoping that someone knew if there was another screw that tightens up the trigger after you get the pins in.
    I have to say that the absence of the trigger hangar made swapping out the trigger quick and easy.

    My first 'real' BR gun had this same issue. The trigger mounting holes are nominally .125 diameter and most pins measure from .1235 to .1238.

    I used .125 diameter roll pins. It tightened the trigger up nicely and the trigger worked better than ever.

    Hope this helps. -Al

    Al Nyhus, thanks I have a good selection of roll pins and will try those. I knew someone had to have seen this before.

    You can adjust the fit of the roll pins (if needed) by widening the gap with a small screwdriver. -Al

    If youíll get some long pins, it will make the trigger easier to change. If the pins are a little shorter than the width of the stock, then you can hold onto the pins while you guide them into the trigger holes. Then tap them with a punch to where they are just lower than the stock surface. The pins might be two inches long depending upon the width of your stock.

    Mike thanks for the advice I will give the longer pins a try.
