the early pre Benjamin sheridans are great guns well worth getting
triggers aren't that bad especially on UK converted ones as the hammer spring isn't as strong
they didn't make a mk1 but there was variations in the c models with imo the early rocker safety with the adj pistons being the better ones but the stocks on the thumb safety were a nicer shape
the current Benjamin pumpers are the 392/7 and the same as the last c9 bluestreak just a different calibre
