I've been thinking about getting one of these for sometime now. I shot my Calico 9 mm carbine today and really enjoyed it although it jammed a few times. I don't know of any weapon design like the Calicos, so they hold a very special place in my collection. Anyway, has anyone shot the 22 LR pistol version? Since ammo is dirt cheap, you could fire away all day and not break the bank. I would appreciate all opinions. Thanks.
