May I pick your collective brain please ? One of my club mates has got a Colt BP pistol that won't go on to full cock when the cylinder is in. When he bought it ( secondhand ) it worked okay for 18 shots.
He has had it all apart and removed any bits of lurking spent caps.
Any idea if it may be a problem with the hand or cylinder lock bit ?
Anyone had a similar problem that they have solved?




Many thanks.
Andrew
