Question: Are the slide and body both metal?
Document: After reading several of the existing reviews, I really wonder if the writers actually own the gun! One says its a 6 shot, while mine holds 15 BBs in its clip. Another one says the slide jammed back and he can't fix it.
The true safety is good for instruction purposes and chambering a 'round' by charging the slide, thus cocking the trigger for single-action is an added bonus. The only way that you can tell that this thing is not a .380 PPK is the barrel hole and cartridge screw in the bottom. Small enough to fit my son's hand, while just large enough for me to fire.
The only problem is that as my pistol's slide somehow stuck in the back of the rail, I had to realize that this pistol was unrepairable, as Crossman was not offering any service for it. I also realized that it was not designed for desperate repair attempts with a screwdriver. (I will try the recommended Pellgunoil (Crossman) lubrication with serious doubts.) I am afraid that now I really got a very, very quiet pistol...
I experienced the same problem with the slide. I contacted Umarex by e-mail. They offered to repair the gun for $40.00 or send a relpacement demo/opened box with no warranty for $32.00 plus $7.95 S&H. The problem is in the CO2 valve, that is why lubrication does no good. Apparently this problem is inevitible. I have used about 10 CO2 cartridges.
With the first hundred rounds or so the slide needed to be pushed a bit to lock the action to fire. This went away as the slide wore in, and it functions fine now.The gun is accurate to about a 1" group at 25 feet, about the same as my other smooth bore air pistols. I think that is great from such a short barrel.I have 6 air/CO2 pistols. I have 2 favorites, this one and my Gamo P23.
I can't believe how real this Air Pistol looks! I bought this to teach my son how to shoot a pistol with (with the recoil and slide action, it truly feels like you're shooting a weak .22 LR) and I enjoyed it so much that I take it to the range for cheap practice (with the price of ammo these days!). It is a very true-shooting pistol out of the box. With the CO2 cartridge and clip loaded, the gun is balanced and well-weighted.
This pistol feels good in your hand. It has a nice weight and sturdy construction, mostly metal. It has a nice action for that realistic feel. It has a hair trigger though. It fires as fast as you can pull the trigger, so you might want to get some extra clips, I find myself empty before I know it.
if the mags were better 5 star, lost a star , also the safety, looks like it where it should be, but is on THE RIGHT SIDE, UGH..STILL IT  PRETTY AWESOME, THE TIMES LOOK OF THE PPKS , AND THE FAMILY PP, PPS PPK/S, POLICE PISTOL KRIMMINALJUST ABOUT THE TIME HITLER, CAME TO POWER, WALTER RELEASED , THE PP. POLIZIE PISTOLEN.. INSTANT HIT WITH THE GESTOPO, LUFTWAFFE, GENERAL OFFICERS, IN .32 ACP , AND .380 ACP.
This pistol is made in Japan, based upon Walther's design, marketed by Crossman. You have a 15 shot, blow-back simulated, .177 cal BB-firing mechanism at 260fps with an incredibly real feel and look. A quick, fun shooting experience that is well beyond the accuracy one would expect from a smooth barrel BB-pistol and all this with a whisper quiet (perhaps the quietest of all air pistols sold) action.
This pistol is easy to load, both the CO2 Catridges and the Crossman Copperhead BBs. The instruction booklet is concise and easy to read. I highly recommend the purchase of this pistol, along with the UMAREX RWS Chamber Lube, the Crossman Copper- Coated BBs, and the a starter box of Crossman 12 Gram CO2 Cartridges.
