Make handguns threaten and noone will even remotely consider using melee weapons.
Yes, I noted that myself. Of course, "too powerful" is a relative term. If his campaign pays a nod to the undeniable--not to mention woefully-unbalancing--fact that in the real world swords have sort of slipped in popularity over the last few years in favor of guns, it may be perfectly for firearms to be the clear-cut weapon of choice. OTOH, it is certainly not appropriate for a campaign inspired by the films of Jackie Chan or Stephen Segal.

In real life, you can choose to run from one patch of cover to another while the bad guy fires somewhere else. The round system reflects that. AoOs with handguns would make handguns able to fire anytime, anywhere, with no need for the time taken to aim or focus -- which is what the 6-second round is normally for.
Just to be clear, I don't think it's a good idea for guns to threaten every square in line of sight. That's a mite excessive. Five feet would be fine. Maybe let Gunslingers threaten add another five as their 1st-level ability.
As a martial artist, I would so much rather be in close combat with a gun wielder than a knife wielder. Ask any pragmatic martial artist and they will say the same.
No, quite a few of them would think you've watched too many episodes of Walker Texas Ranger.

Face someone with a gun pointing at your torso, with that hole at the end looking bigger than life itself, and you'll realize--quite pragmatically--how you are just a finger-squeeze away from mortal injury.
Yes, a gun wielder who is fifteen feet away and has you flat-footed has you at his mercy -- but a gun wielder in the middle of a chaotic combat who is five feet away from me is nowhere NEAR as dangerous as a knife wielder in the same situation. A knife can cut me along a lot of different edges, while a gun's danger zone consists of one line.
Nowhere NEAR, huh? Ah, the ever-distinctive over-technical combat pseudo-analysis of the "pragmatic" martial artist who's maybe 19 and thinks he's got it all boiled down to a fine science with trajectories and what-not. Your proclivity for speaking in terms of extremes and absolutes in this matter is telling in and of itself.
Sure, a totally inept (non-proficient) gunman may use his weapon clumsily in a "chaotic combat" (real combats are usually over in seconds, which is really too quickly to be qualified as either chaotic or orderly). He'll either snap a shot off and drop you or you'll attack his gun arm and eliminate the weapon from the fight.
But a cold-blooded shooter? Chances are he won't conveniently extend his arm out toward you to have that little double-handed slap disarm maneuver pulled on him. He'll keep that gun down and close to him and drill you, and believe me that bullet's "limited danger zone" will seem a lot more dangerous as it rips through your guts.
This is worth a different thread in an of itself -- if you think I'm full of it, we can take it elsewhere.
Actually, it's not worth a thread. You're reducing the fairly straightforward art of close-quarters combat to an overly-elaborate, choreographed, pseudo-science in an effort to rationalize an extremely bad move as a sensible tactic. The truth is, you don't need to talk to an experienced martial artist to know what the proper working theory is in this scenario. Hate to take an ascerbic tone with you, but I'm genuinely concerned that you might try this in life, young man. Please don't. You will find that there is no deep strategy at work and will likely either die or be gravely injured within a couple of seconds.
3) Ranged weapons and melee weapons are different, not just in the game, but in real life. Taking a swing at someone next to you does not take a ton of thought -- if someone drops their guard to do something (like move through a square you threaten) it's relatively easy to lash out at them. But ranged weapons require more thought in terms of aiming and focusing
No, a .38 special is not harder to lash out with than a rapier. Simple point-and-click inteface. Doesn't get much simpler than that really. POP! You're down.
I'm not utterly against the idea of ranged AoOs -- I recall that some prestige classes in D&D made them possible, and I'd be fine with an advanced class or prestige class that did the same here, or a feat that made it possible. But it should not be a low-level feat -- anyone who can keep track of 60 squares at once ought to be darn powerful and ought to have spent a lot to get to that point -- high level in the advanced class, or a feat with a high BAB pre-req, along with Combat Reflexes and ranks in Concentration or something.
For the most part I'm in agreement here. Reality probably should give way enough in this case to require some feats to be expended. I think a five-foot threat radius should be simple enough to come by. In contrast, AoO's out to 60 feet would be disastrous regardless of any qualifications.
