Are you suggesting that people that interpret the rules strictly end up being shot to death? Why even tangent the discussion by bringing up that tragedy?
Presumably you're trolling at this point. Or don't know much about Barthes' work. Or his death, which was a result of getting hit by a car in 1980. Or all three.
Items that install to the integral slot aren't accessories. Accessories are, by definition, added on to the top, under, or side slots. Because of that, modifications (which go into the internal slot) don't get limited by the rule on page 51.
Untrue. Again, see the description of the GunCam on page 52 of Run & Gun. It is an accessory and it can be placed in the internal slot. Also see the much-discussed sidebar on page 51, "If you add an accessory to the stock, barrel, or internal slot,
or add a modification...". Emphasis mine. This clearly distinguishes between the processes of adding an accessory to the internal slot and adding a modification. There is never any mention of an accessory becoming a modification if it's placed in the internal slot. I think that makes sense, but I'm not the one arguing for a strict reading here.
No... smartguns are an accessory that existed before "modifications" even was a term in Shadowrun. The core book does state that a smartgun system can be used internally (which would mean the internal slot), or externally (using either top, bottom, or side).
But you've already eliminated the possibility of light pistols having an internal slot by citing the bit in the sidebar as an exhaustive list of where you can place an accessory. If they can't mount on the side because it's not mentioned, they can't mount internally because it's not mentioned. If you want to retroactively make internal smartgun systems a modification and not an accessory, I'm all for it, but you're now breaking your own rule regarding the authority of the text. You can't pick and choose when you get to have an absolutist reading of the text and when you don't.
It creates no fissues as I see it. The only fissures are there because you are ignoring a bunch of those moving parts.
I'm not sure I follow. I'm the one who keeps citing passages from the text. Your one counterargument--"Accessories are, by definition, added on to the top, under, or side slots"--is unsourced and demonstrably false.
