You can see in the picture with the yard stick, the overall size of it isn't very big. I have the russian commercial model which allows use of double stack magizines. The origonal military models (to the best of my knowledge) only used single stack magizines. the difference is that a single stack model can only use mags that hold 8 rounds. A double stack model can use the 8 round, 10 round, or 12 round magizines. So i toss one in the chamber and with the holster i'm carrying 21 rounds on me at all times

Accuracy....i'm pretty good from 15 yards with this thing. I'll put it this way, from 15 yards, i can dump 10 rounds in rapid fire and about 6 will hit you in the chest. not bad for a short barrel that only has 1/2 twist on it :P
