Tell you why I think the Crossman 1701 in perfect,it is light ,very accurate, can get a lot of shots and is hand pump friendly.
I have most of all the pistols mentioned,one problem is BALANCE....which I feel is very important for offhand shooting....remember a great balance...also remember a red dot or scope should not negate the balance.... more the length of barrel may through the balance off..
Also Crossman Co2 pistol may be the way to go....What about loudness,it is easier for me to shoot a quieter pistol.....
Balance, weight,loudness....accuracy,parts,Easy fill....Fit,parts ,custom grips...etc.....how hard is it to load.....all are factors...
A say get a cheaper Crosman CO2 pistol to start with....get custom grips,whatever sights work for you=Not out of too much money and it is a great start.....
