snowman69 - my experience with them is limited to one email which I sent asking if I remove the rear sight on my pursuit, do I need medium or high mounts to clear the hammer. Gave them the name of the mounts I was looking at. The reply - try medium, if not, try high. Hmmmm - thanks a lot. While we are on the subject, should this happen in the field, with an inline I guess you just pull the breech plug and dump the powder charge or pellets. Don't as yet have a tool to remove the slug itself. What do you use?
