I have a Kahr K9 Elite 98. It is a great gun, but it is a little heavy. Just how much lighter are the P9's? Will I really notice a difference? Trying to fight off the polymer urge....That new Ruger looks pretty slick. Sig 250's are cheap right now. My brother has a Glock 26 and likes it.. Must ...fight... off ...urge to buy another gun....
