I have had my Umarex Walther PPK, CO2 BB gun for more than 3 years. I have a bit of a different opinion of it.
I think it is exactly what it claims to be. A replica BB pistol. I have never handled the real firearm, so can't comment on the exact comparison. But it is a fun compact CO2 BB pistol, with snappy blowback action. I found it to be reasonable in accuracy, compared to other similar replicas, some costing a lot more. I shoot it on a 24 ft. basement range, and it's accuracy is as good as my Glock's (17 Gen 4 & 19x), as well as my Beretta 92A1. And I don't have a problem with it's velocity. Although I don't have a chrono, I feel the velocity isn't an issue. I would guess it is around 300 fps.
I'm not sure what everyone everyone expects from a CO2 blowback replica BB gun with a smooth bore barrel that is around 3" long, and can be bought for less than $100 CDN. I was very happy with my purchase.
I get around 100 good shots from one CO2, which I feel is pretty good for a blow back CO2 pistol. And spare stick magazines can be bought a reasonable price.
Only complaint, is the Walther laser specifically designed for it. I replaced the trigger guard with it, but it never held it's zero for me, so I removed it. If some wants it I can sell it to them at a good price.
Finally, Princess Auto is clearing it out for $75.
