I have never been disappointed with any the High Standard revolvers old toggle release Sportking, or button release Supermatic Citation pistols.
You have to appreciate/love the ease of dissembly and cleaning the the newer HS semiauto's #1 retract slide and lock open, #2 drop mag, #3 press the barrel retainer toggle and or button, remove barrel, #4 ease slide off the frame) just try doing that to a Ruger Mk1/II/III or the Browning Buckmark !
Even had a old FIE Buffalo Scout that was a fun shooter.
I had a Ruger Single Six for a few years that was one the most accurate single actions Id had (sucks its 6 shot)
Today Ruger makes the double action LCR 22 and SP101 in rimfire as well as a updated Single Six with 4 more bean holes 'the Ruger Single Ten'.
Ruger's MkIII 22/45 Lite, the Ruger Charger, 'a pistol version of the 10/22 carbine'.
The you have the USFA Zip 22 that utilizes the Ruger 10/22 mags.
I have a shooting buddy that likes his Heritage Rough Rider .22.
One the guys has one wicked accurate Keystone Sporting Arms Hunter Pistol a 'Cricket bolt action single shot pistol.
And though they catch some bad press, I have a Taurus 941 Tracket that so far has been one my favorite rimfire double action revolvers.
And I had fun at the range with a friends Charter Arms Pathfinder .22 mag double action revolver.
And I love my shooting buddys Colt Cadet .22 pistol (kinda like a High Standard in a way) and not such a pain to clean as compared to his Buckmark. Which is a fine pistol, just not as handy to clean as the Citiation/Sportking or Cadet.
For one my all time fun .22 pistols was a used Intratec TEC-22 with laser sight, that bullet hose was a blast.
At one time I had a Calico M-110 is another fun and mostly reliable bullet hose (though sensitive to mag abuse *thanks to my kids over doing the spring when loading
I pretty much cleared out my high capacity 50 rounds + fun guns during the .22 rimfire drought over the last 5 years.
I did shoot a Grendel P-30 (30 shot .22 mag Semi from the early 90's) that was ammo sensitive.
Ive read good things about Kel-Tec's PMR-30 pistol (anothe .22 mag semi)
