Just picked it up. Comes with 2 barrels, 22TCM and 9mm. First impressions out of the box, this gun has a very nice trigger. Much better than the trigger on my RIA tactical. No creep and breaks at about what feels like 4 pounds.
The pistol is high capacity. Holds 17 rounds in the mag. The 22TCM round comes out of the pipe at around 2000-2100 fps. At 100 yards it's still going over 1500 fps. And this is out of a 5" barrel.
TCM 22 ammo was plentiful at my LGS. $21 a box (50 rounds).
