I have two air pistols in the house. The top one above, a beautiful old Webley, is rarely used; the one below, a cheap German job, is used by my grandchildren in the summer for shooting at tin cans.
The old Webley is almost an antique. It dates from the late 50's/early 60's, and came into my possession in about 1980. I bought it at an isolated petrol station in Wales, from the owner who seemed to specialise in selling such things (other than petrol). It shoots .22 slugs, is very heavy, and extremely accurate.
The German job is total rubbish. I bought it new in about 1990 as a diversion for our summer visitors. It fires .177 slugs which can be seen exiting the barrel before falling onto the ground a few feet off. Even if clamped to a vice its bullet will not follow the same trajectory more than once in every 100 shots. It's perfect for a bit of fun persecuting tin cans, whilst, at the same time, teaching the users the essentials of gun safety.
Yes, they are definitely 'boys toys', and we have a lot of fun with them. Otherwise they just sit at the back of a drawer waiting for certain boys I know to come visit their Grumpy.
