call kolar @ 262-554-0800 and ask to speak w/ Keith Sprangers. He designed the trigger, and can help you out. The kolar triggers work perfectly right out of the box for 95% of shooters, but those 5% who have problems either experience the 2nd trigger not setting (trigger reset too slow), or doubling/fan-firing (trigger resetting too fast). Also, you said like new, did you purchase this gun new or used? If used, theres always the possibility someone monkeyed w/ the triggers. My guess is your holding the gun loosely to your shoulder, and/or shooting handicap-level loads which is exaserbating the problem. This is usually a 5 min fix @ kolar to change out the block that dictates reset speed. My friend had to have his changed to reset faster, i had to have mine set to reset slower (or maybe it was the other way around, i don't remember, it was a LONG time ago LOL).
At any rate, don't despair, help is only a phone call away.
Gun was shot as new - trigger was light oiled - cleand in new parts cleaner , shot dry , same results . Gun fires both barrels - and has a slow lock time . Sending it to Kolar tomarrow . Thank every one
My sporting clays model fan fired for me too once in a while. It only did it when shooting sporting clays(shooting at an over head target). I cleaned the trigger and got too much oil on it then it fan fired every time. I sent the trigger group back to Kolar and they installed an inertia block. This would slow the trigger down so it would not reset for the second shot so fast. This small delay would prevent the gun from bouncing off your shoulder and the trigger hitting your finger causing the second barrel to also fire. This all happens in a fraction of a second making it seem like both barrels fire at the same time.This up date has solved the problem for me . I just sent in my trigger group and got it back in a week. No charge for the up date. I talked to Jeff M about this and he told me that only certain people have this problem .They really noticed it with their sporting clays guns ,with all the different shooting angles and gun positions. Hope this helps. Jeff I
