Of the two you see far more CP88's used in IPAS - a nice handling gun that with the exception of quirky slide release has a great reputation for build quality and reliability. In my opinion the 92 isnt so well screwed together and is a little cumbersome though I have to admit that it looks great - especially in nickel finish with wood grips. IMO its CP88 for function and 92 for looks - however as has been said best to handle both and see what takes your fancy (and as Richard says, you could always buy both....)
