Well I've found that both the P7 and P210 are really cool guns IMO and also a little querky.
P7 querks:
A) gets hot with excessive shooting
B) gets very dirty very quickly
C) leaves an odd black mark on the web of the shooting strong hand
D) expense
E) hard to find a good deal
F) the M8 is really hard to get at a fair price IMO
P7 cool:
A) Awesome looking
B) awesome engineering marvel
C) safe gun considering the cocker must be squeezed prior to going into action
D) accurate
E) handles well/points well
F) seems to hold value well enough
G) a bit of a cult pistol with some real obsession behind it (if your into that kind of thing)
I might add a few to your list.
Pro:
Works fine when extractor broken or missing due to fluted chamber
Does not matter whether you squeeze the trigger or cocker first, will fire when the other is pressed. (Yeah, pull the trigger, then pull the cocker to fire it.)
Very thin gun
Built like a tank
If you lose it in a fight with a turdball, he may not know how to operate the gun possibly saving your life.
Con:
Not very many aftermarket grips and accessories
Some will not like the European style magazine release on the heel
Heavy
