well that simple update may make previous design obsolete....

but err.....

 

advantages to the previous design:

 

1. whichever is already in stock + production = speed.

2. tested already. there is no jamming.

 

version 2 however, requires some R&D and testing......

 

no good if the spring mechanism jams because the cartridge

is too long. it becomes a bit too unpredictable.

 

P90 cartridges were perfected already with alignment of 2 layers

of ammo i think......

 

but if to combine multiple cartridges.......

 

quite a risk but i think it's possible..............
