I'm trying to decide something. Currently I have a Ruger Vaquero Bisley SA revolver in .44 mag. Shoots okay though a little low for me but I can fix that with either handloads or a file (I'd have to do a BUNCH of firing from a rest before I go this route). However, I would really like either a Ruger Redhawk or Super Blackhawk. I am considering selling my Vaquero to fund this, but there is an issue - the Vaquero is no longer made in .44 mag. I am wondering if the value of this gun could go up over time, making it worth keeping. I guess my question is - should I hang onto the Vaquero with the anticipation it will increase in value?
