Light Arms, Side Arms, two versions of Black Market Munitions, Kemwer Munitions, APM Advanced Hardware all already extant...and you think another version of weapons will "spruce" things up? Sounds totally boring to me. I suggest thinking less generic and more specific. Perhaps a weapons line specifically geared towards assassinations or covert operations, or effecting especially gruesome deaths as a statement - something that really sets it apart other than 'we made this to sell to you instead of them making this to sell to you.'
But that's purely an aesthetic opinion on my part; if The Coalition official faction wants to make this an official request (which only requires that it say so here, since I'm not sure you posted as an individual or official rep of the faction), then there's no problem with it from any functional standpoint. Four destinations is wholly inadequate though. At least expand that to all of the revolutionary groups on the Coalition's allies and friendlies list (which I presume is much longer than just LWB and Red Hessians). And by the way, the routes from O52 to the LWB and Red Hessians would not be very risky, so wouldn't get top profitability. I'd have to look at them more technically, but I'd guess those two would be in the low 300 range, with deeper ones in the Houses being closer to 400.
