I HATE YOU!
I mean the M3 grease gun is just cool! The star of such movies as "The Dirty Dozen!" If its cool enough for Lee Marvin and his boys, well thats enough. Although the ol Thompson is sweeeeeeeeet! Damn you sir for making us choose!
As for going into a fight, I'd take a MP5 for the T2K world simply because they are available in quantity, as are spares and ammo, and of course the select fire option and HA-HA-HA I have some trigger time with them.
Accurate! Although the M16 carbine version is kinda cool too and heheehehe, I am making one
<M4 size in 9mm> it is familiar to say the least.
But, the MP5 is it, although yes the caliber could be better, a true MP5 in .45 that would be as plantiful as the MP5 is oh what a wonderful world it would be.
