Researching trigger improvements for my C9 has me confused. I purchased this C9 new from a dealer some 20 years ago (more or less) and I am very happy with the power and accuracy. However the trigger has a lot of creep and is quite heavy, too. The confusing part is that mine is marked "Benjamin-Sheridan" and has a 9 digit serial number, all numbers, no letters. Looking at the serial number history on the Crosman site, none of the serial number sequences seem to match the serial number on my C9. The only serial numbers shown either have a letter preceding the number or there are only 6 digit numbers. Also I can find no reference to C9's having both Benjamin and Sheridan imprinted on the air tube. It's either "Benjamin" or "Sheridan", not both. What I've been searching for is a "how to" improve the trigger....to lighten and remove all that creep. Does anybody have an answer?
