Are both capable of fitting the stock mags?
Did you purchase in Canada? I am trying to figure out a way to purchase the grip module and "safely" bring it across, but the laws are so confusing, especially with the P320 having on the FCU serialized.
I have to say I like the look of the GreyGun, but the Wilson Combat looks more "grippy". Did you have the stock grip before or the x series grip? If I cant get the P80 these are pretty much my only 3 choices from the stock sig frame.
