hi guys i have just purchased a falcon fn19 single shot in .22, i have never used one of these or known anyone who has one so i know nowt basically on the performance of these guns. i paid £300 for it in good condition with silencer, 2.5-12x50 scope (German reticule tho)real tree gun bag and rws stirrup pump does this seem a fair price? any info or comments on improvements or mods gratefully received
