The rimfire pistols/revolver's I've had are...
Heritage 22lr/22mag, never any issues, still own.
Ruger single six and single 10, never had any issues, both were great but heavy (don't own either any longer.)
Walther p22, after about 1000-1500 rounds slide failed, learned the slide was made of zinc. (sold off the parts) loved this gun, so disappointment to find out it was Zinc.
ruger sr22, maybe 1-5 jams out of 1000+ rounds (could have been ammo or limp wrist). not ammo picky slide is solid aluminum (sold because its Prohib in canada)
colt woodsman 1931 man. year, yes jams a tad bit but nostalgic, perfers standard velocity ammo. (gifted to a friend)
issc M22 (glock looking) POS, it was cool looking and neat concept but poorly done, it only liked Premium High velocity and only on a day that the sun lined up with halleys comet, and 3 unicorns were within 100 yards...(if you get my point) LONG GONE
Other then that, I've shot many Buckmarks and Mark Rugers and they all fired Flawlessly as well, If you go the revolver route you shouldn't have any issues, for example the Heritage is Probably one of the cheapest guns made ($99) here in Iowa on sale and I wouldn't sell it for anything, a: not worth it cause its el cheapo to begin with, and B: its so fun for everyone, easy to shoot and not heavy being made of mainly alloy (except barrel/cylinder) mine is the 4.75". and lastly, it has the ability to become a 22mag within less then 1 minute just by switching the cylinder, I know in canada you cannot pistol hunt but its an awesome rabbit gun, and even a lil funner on the range in 22mag.
I will be buying a new Ruger sr22 (long slide) to replace the one I had before I move back home to Canada this summer because again that gun is super light, super reliable and loads of fun for Youngsters to shoot, it also mimics modern handguns, this time it won't be the (lady lilac model) daddy will prevail, this time.....lol
I'm not sure if the new SR22 Long Slide is Available to you up in Canada yet but hands down it has been NONE picky with ammo and super reliable, it fits perfect (has back straps to modify grip) and plinks better then most. the jams I occurred very well could have been the ammo or most likely limp wrist, they only ever happened when kids or unskilled fired it....go figure, we have a few ammo cans of crap ammo that usually got feed to the sr22.
