I recently installed a bellm oversized pin in my encore and have to say I am impressed with it. My groups went from 1 1/2" to under 3/4". But I have a problem, if I normally open and close the gun I cannot cock the hammer. I have to slam the gun together to get it to cock. This started when I put the new pin in the gun and was wondering if anyone else has had this problem and what the solution was. I have a bullberry barrel with hanger bar on it also.
