My wife ought me a Walther PPK last Christmas... (with the laser sight) to replace my 25 year old Crosman 1200. 'Not happy with the PPK at all. 'Doesn't seem to have the range nor the velocity of the Crosman. The laser is worthless. I've tried that from a gun rest, but usually anything past 20' is anywhere but where I point it. The C02 ctg is difficult to seat... 'foolin' around with that internal length thing, then twistin' that infernal butt plate doo-dad. I use Daisey C02 ctgs... 'no ruff edges but gettin' a decent cartridge puncture is a trick. I'm gonna be buyin' another Crosman. The Walther is OK for point-defense practice at close range... no aim, just pull, point 'n shoot. (Open carry is in the Arizona Constitution... Article 26. I have an AZ CCW permit also...)
My 'normal' carry gun is a Springfield Armory 1911-A1 in .45 acp, which is a tad largish to conceal anywhere.
