I'm actually talking about Rogue Trader rather than 1st ED 40K.
Given the number of times I've seen the confusion, I'm in the habit of referring to them as Rogue Trader RPG and Rogue Trader 40K these days.
Because sometimes you just want something with a bit more punch
Maybe, but that doesn't mean it would be an Inquisitor's main carry weapon. Given that the problem in a typical firefight is more likely to be hitting the target than killing it, a weapon that would be overkill, more conspicuous and which you can only carry a fraction as much ammo for would be counter-intuitive.
Anyway, most of my warbands tend to have a way or two they could reasonably put down tougher targets like a Space Marine, Ork or Daemon in the unlikely event they should run into them unexpectedly, be it special ammunition, grenades or creative use of psychic powers.
But sure, when they're
expecting tougher opposition, they'll up-gun as necessary or get in hired help. (Cortez will doubtless recall the Battle Sister and her chainsaw bolter.)
The same type of pistol that Private Joe Guardsman carries as a standard sidearm is less cool.
I don't know about that. If there's a fluffy reason for having such a pistol, then it's fine by me.
Dark Heresy allows for rather a lot of variation in laspistols
Given my own Revised Armoury had about ten thousand laspistol variants in the last edition, I have quite high standards about what counts as "a lot of variation".
In my opinion, that's more a problem with the armoury and damage rules in Inquisitor than with the weapons themselves.
Not sure I agree. Bolters should be lethal, and I wouldn't want to see them nerfed for the sake of trying to shoehorn them into game balance.
They should be treated like they are... lethal but very conspicuous weapons which are exceptionally valuable and frequently hard to resupply.
