In .22's the current stash includes :
Ruger standard model, pre mk II
Sig Trailside standard model
High Standard Military HD
Beretta 70S
Beretta 76
and the newest addition Walther P22
And over the years I bought and gotten rid of several more (including Browning and Pardini), I'm sort of a .22 pistol whore.
The Rugers are a good plinker, but as already mentioned none come from the factory with a decent trigger, I think they have a crappy trigger policy for all firearms. But there are lots of extra gadgets you can buy for them to turn them into absolute tackdrivers. Actually you can buy enough bits and pieces to make them cost almost as much as a Pardini or Morini.
The Trailside is decent (now), although it had to have some repairs done due to FTE issues(I bought mine the first month or two they were available). I really like mine, but it may not be for everyone. My opinion, not backed up by any facts are that it isn't as "tough" as a Ruger, for instance. But since I don't abuse my firearms it's not an issue for me. It's more accurate than any of the stock Rugers I've shot over the years, but keep in mind I have not shot a MKIII.
The Beretta 70S is the short barrel model and is really a lot of fun. It must be some wierd Euro idea of a small bore carry gun, a nearly full size/short barreled pistol in 22. Accurate and reliable with a decent trigger.
Beretta 76, if you can find one of these used buy it, an excellent trigger, not a true target trigger like a Pardini but close. Every one I see is around $450-550 used though.
The High Standard is simply the cream of the production gun crop. Mine is vintage 1948 and will still shoot with any current production gun, by far the best trigger of the bunch, and the most accurate.
The Walther is quite a surprise, I tried one when they first came out and it made the Ruger seem like a match quality trigger, absolutely horrible, long, heavy and gritty. But about a month ago I was in my local shop playing with various pistols and tried one, now they have a pretty deccent plinking trigger, definately not target grade but better than most factory Rugers I've tried.
It seems reliable with Stingers, Minimags and Eley Pistol and Match ammo, accuracy is decent but definately not on par with the Trailside/Beretta 76/ High Standard. The grip is a little narrow for my taste, but the daughter loved it. You can also unload it, apply the safety and dry fire to your hearts content.
I didn't like the Browning standard model I had, but do like the target models, all I have shot were reliable and good accuracy. A friend bought a Neos and it seems to be a reasonable plinker, not terribly impressed with the trigger , but fairly accurate.
Just one mans opinion, yours may vary.
