I don't know what it is about the GAP. It seems to be very accurate and have a little less recoil. Also uses flash suppressed powder that won't blind you in low light.

I must admit, I have not shot the 45 GAP, but I have shot the 357 sig and I find the tokarev comparable and more available.

The 10mm is just a 40SW on steroids and is way over powered.
I prefer the 40 which is plenty damn peppy and then some.
