Really I was enquiring about a different barrel ... but a handgun for the calibre is much harder to get a permit to acquie here ...

Haven't looked into lengths, but I might guess the carry version might be too short to have here. However the other models should be possible.

I am a pistol novice, however I still steer towards a proper steel handgun to start off with.

The SIG would also need to be available with handicapped 10 round maximum magazines for here. I do believe these are available. I am sure I have seen P320's for sale soon after introduction.
