I dont know if this is the right place to ask or not , but any help would be appreciated , awhile back I bought this mod. 10-8 , to say it is well used, may well be an understatement . No matter ,my question is what is a fair price to pay for a new cylinder ? There is a considerable amount of play(rolling it side to side) when the hammer is cocked in SA . You can see small burrs or lips on the cyl. notches where it locks up . I plan to replace the cyl. stop too . Thanks
