Found a video of the SMG used in Competion at Knob Creek

Here is some footage of the Kriss SMG used in Sub gun competition.

Needs to practice his magazine swaps.  ;)

That's where a KWA Kriss would be handy, I think, for practicing.

The problem with using the KWA is that you dont want to drop the mags. They dont like to be dropped. As they hold gas inside. You might damage the seal.

A friend went there. You can only use full auto. I think it is a waste. I would rock it on 2 rd burst.

Well, when I want to get better with mag-swaps, (FIRST: make sure the gun and mags are EMPTY!) I just hold the gun over my bed or sofa (watching tv) and drop the mag out onto the soft surface. Usually with my eyes closed, or not looking at the gun directly.  ;)

Haven't actually done that much with the SDP yet... I need to.

Practice is better than no practice. KWA is expensive practice haha. Also the mags weigh a couple pounds as they are all metal. So it would be like dropping a full mag. Best to practice with empty mags.
