Took another look at this Snow Peak knock off of a Diana P5 and the scope in the ad looks alot like the scopes that the vendor sales with his rifles. So if that's so the scope is useless with the pistol. Not enough eye relief. Also, the scopes are useless on the rifles. I know B1's and 3's. The 11mm scope grooves don't go back far enough to get proper eye relief with those short scopes.
It reminds me of my old IZH Baikal MP 53M I bought years ago from PA for $50-. PA spes: 2.67lbs, 16.02" long, barrel 8.46", 360fps, trigger 2 lbs, no scope rail.Can't remember chrony numbers but it shot RWS alloy pellets pretty good.
I tried to buy a Knicklauf Pistole Diana p-five, Kunststoffgriff, Kaliber 4,5 mm (P18) in Germany from versandhaus-schneider.de, it was in back-0rder then, and still is now. When I noticed Kralle offered the Artemis SP500 last November I ordered one at once and cancelled the German order.Mine does not smoke, looks rather nice, very cheap, accurate, not bad at all.
