So I've noticed its conventional wisdom around hear that Automatics is the best guns still because it lets you use the supposedly concealable machine pistol. Well I've been thinking about the numbers, and I'm starting to question just how concealable they really are.
Lets take the average non-samurai runner. Deckers, mages, some riggers, etc. Characters who probably never invested in AGI and have it at 3. If they default on a roll to conceal a Steyr TMP, They've got two dice. The average human being at this point has a 50/50 at spotting that thing at a casual glance! Not a fair comparison though, all things considering.
So lets up the ante a bit. Our non-sam decides it might be prudent to know what the hell he's doing and gets some palming training, specialized in hiding shit. Now he's got 6 dice to stow that TMP. Vs the average citizen, its 6 dice on 2. Pretty damn good odds, unless our citizen is casually perceptive. Its not too unreasonable to assume that some of us here have 1 perception, so not defaulting on those rolls means they'd have 4 dice. 6 on 4 is still advantageous, but personally I tend to get nervous when my lead is only 2 dice, especially on a roll that can blow my cover! And this is still average citizens we're talking about! A bit of crappy corporate training (prof-2 corporate security) and that 4 bumps to a 5, making that comparison even closer! Get some experience on an actual street (prof-3 police patrols), and now you've got a 6, meaning that a guy with a gun and cuffs now has you in a 50/50.
At this point, the concealed carry holster is an absolute fucking must! And even still, while the 6 on 3 is okay, I've already talked about how I'm not fine with 6 on 4. Now do this with a light pistol, and you're pulling 6 on 1 with the corp sec and 6 on 2 with the cops. MUCH better! Do it with a holdout, and these people literally have no dice!
Now if you're a nova hot street sam, you're in much better shape...kinda. Lets be honest here, how many street sams actually consider palming? So lets consider a minmaxed badass with 9 AGI who stows is TMP with 8 dice. Yeah, remember what I said about 2 dice leads? 8 on 6 with cops is alright, and better with corp sec with 8 on 5. Once again, concealed holster that shit! I think I could live with 8 on 4/3. Or better yet, consider palming with a specialty! knock that 8 up to a 12, baby! 12 on 4/3 is much better! Shit, at this rate I can almost see what people are saying 'bout machine pistols not sucking at this.
But then lets get serious. The most deadly foes to shadowrunners sure as shit aren't beat cops (even if they are some of the most common), but even their lieutenants give us trouble! The professional rating 3 lieutenant pulls 10 dice on perception checks! OUCH! For all those sams who never considered palming, they're dice pool here is even with the concealable holster! And while 12 on 8 is good, it still makes me sweat bullets a bit. If given the choice, I'd much rather be packing a holdout to get that down to 12 on 4. Though at this point I should mention that physically patting a person down cuts concealment in half, so even that holdout is giving us a 12 on 7. Oh, and don't get me started on the non-sams! A concealed holster for your TMP against a pro will get you a 6 on 8 or a 2 on 8 for the untrained plebs! Have fun getting your shit found!
Its gunna take a person who really cares to make concealing work against the most determined security. AGI 9, Palming (concealing) 5 (7) provides 16 dice, giving our pat down victim a 16 on 7 with a concealed holstered holdout. Now those are odds I can live with.
So in conclusion, while particularly agile characters might regularly sneak Steyr TMPs past beat cops and corp sec, a determined search by an actual professional will give you a run for your money. As for the rest of us, I say don't bother. The average person with no clue what they're doing will get spotted by average people with no clue what they're doing, and getting a clue will only provide a marginal benefit against people who have a clue. I might be in your best interest to just pack a smaller gun.
