I have the SR22.
Not a single failure of any kind while using 4-5 different brands of ammo.
Its a fun gun.
Others for you to take a ganger at....
I also have a Bersa 22lr. That one is all metal. Nice classic styling (to me at least). Runs well with the higher velocity ammo like CCI mini mags and Blazers. It hasnt like the really really cheap stuff but other peoples' have.
I also have a Browning Buck Mark. Similar to the Ruger's but a little more 'normal' looking in my opinion especially if you get one with a 4" barrel.
You may also want to take a look at the S&W M&P 22. That one is more combat looking like the SR22 but a bigger size.
The SR22 and the Bersa are small.
The Walther P22 is very similar to the SR22 but not as good.
