[quote name='Temporaryscars']I was thinking about a Walther P22.[/QUOTE]
I shot one of those with a suppressor on it a several months back, unbelievably fun.
I still want one. I really like the OD green and flat dark earth models but I'm torn because the Sig P226R-22 (which they put out because the Mosquito is garbage) is really tempting since you can get a 9mm/40S&W upper, mag and barrel and use it as a true tactical .22lr trainer.
The Sig is full size though, where the Walther is about 75% the size of the P99 and almost identical to the PK380. So if you want a compact plinker, the P22 is more ideal.
