You do realize you are not allowed to quickdraw a Panther right? Pistol sized weapons only, and the Panter is XXL not pistol sized.
I realize that. Which is why I discussed my concept for the weapon at length with my GM. (His game, His choices) He said he'd allow it and placed his conditions for it's use.
Melee Hardening? I would say add a Bayonet.
Considering how much that weapon system cost, I'd rather make sure it can't be disabled if it HAS to be used as a striking weapon. While a bayonet might make practical since, in this case I decided against it, because it cost more than I had to spend, also in the end the PC has got spurs, and a sword. both of which can be utilized separately and more effectively than from the panther. I'm not saying you're wrong to choose a bayonet, but at the end of the day my PC would much rather push someone away and shoot them for 10P -5AP than keep them close enough for a blade fight.
Iajutsu aside, the standard consumer can not quickdraw a PantherXXL so I highly doubt there even EXISTS a quickdraw holster for the PantherXXL.
Here is way I describe that quick draw holster. It's a troll size duffel bag, the inner core of the bag is the panther, surrounding the panther are 2 pieces of a rough foam cut out that on the sides molds to the weapon, making it look more or less like a well packed bag, implanted in the foam are RFID tags that read as clothing, food, and some other random junk so if it gets scanned by a tag reader, it'll read normal stuff. (Before it comes up. Yes my PC bought the weapon clean from the black market and made VERY SURE that it had no RFID tags inside the internal parts of the weapon.) The weapon's sling system looks like it's the bag's strap, but is actually fed through the slits in the bag that allow for the bag itself to fall away when it is unzipped. When the gun needs to be brought out, the PC just unzips the bag. once the nylon "bag"(case) falls away, the foam falls away, which leaves the panther completely un-holstered, and ready to make people into salsa.
The only thing that requires real modification to the bag is the part where the sling slides into and out of place, otherwise everything used in it's design can be found between a sporting goods retailer (bag), a clothing shop (for the misleading RFID's), and a parcel shipping company (the foam to encase the weapon). No it won't hide the panther from a visual search, conducted by a person, or the proper scanners, it's not meant too. but I wouldn't want to be be the guy who rifles through a bag that looks like it's carrying someone's smelly, dirty laundry...
otherwise, it does exactly what i need, keeps that big ass gun out of sight, out of mind for all the people walking down X street. Since the PC doesn't carry it into area's where KE and major security operate unless he can smuggle it around. that doesn't matter much to him.
I didn't think my last post was gonna be the cause of such a hot bed of discussion. I hope this all explains it better.
