Honestly, I've been calling for Bond to start carrying the ASP in films for years now and have little reason to cease! It'd be perfect for him, and while it's not as iconic as his two Walthers (which I don't want to abolish entirely, but I've always argued the P99 shouldn't be his constant-carry weapon) it's a stellar handgun who finally needs to see some screen time.
Yes, the ASP would certainly be a good choice. But as it's out of production I don't see that happen. After all, even the coice of handgun is a question of product placement and merchandise. EON Bond will only wear what the modern market can provide. I for one would already be happy if they stopped Bond drawing ridiculously large full-size service autos from shoulder holsters under ridiculously well and lean cut expensive suits that clearly didn't cover those guns till the scene was shot. This is just an 'Inspector Gadget'-thing and really ludicrous and annoying. It's either well cut suits and slim line gun or full size indoor FLAK and Jack-Bauer's-Secret baggy fashion. Only very few people can have both.
As much as I would probably be screaming with enthusiasm if they ever showed Bond with an ASP, since EON seems fixated on Walther, they should at least have him use the PPS instead of the gargantuan P99. While I'm only so-so on the trigger feel of the PPS, I will grant that it is a very slim pistol and certainly capable of being concealed nicely.
Like almost everything else in movies today, Bond's guns are certainly a subject to a contract with Walther in the same way his cars are contracted. If that contract expires, all bets are off again but Walther has of course the same benefit of the classic heritage Aston Martin has. I doubt very much that either EON or Walther will ever dare to break that lucrative agreement.
