I know you are set on buying new, but there are a few more to consider if you widen your search to include secondhand
Any Diana/Original model 5 or 6
Weihrauch HW70
Or if you can be tempted away from spring piston to SSP (Single Shot Pneumatic) then either a brand new Beeman P17, or a secondhand Weihrauch HW40 will outperform most, if not all the pistols in your original shortlist
TX200 .177 21mm TL | TX200HC .22 22mm TL | Prosport .22 22mm TL
HW40 | HW45 | Diana Mod5 | Webley Senior....... Because PCP is like kissing your sister (apparently)
