9 doesn't penetrate sheet metal consistently enough to work as a dedicated carjacker caliber so I like .45 for the dedicated carjacker pistol.

I started with a 17 thinking that the 19 wouldn't make that much of a difference for concealed carry but it does. Once I had momentum with 9s, I just kept going. Roland Special was originally a 9. Also, the gen 5 I have configured as a dedicated lefty. I can operate it right handed if I have to, but it's a lefty/dual wield option.

Nice thing about the Glocks is the compatibility everywhere, including in the KelTec Sub2k style pieces. As a "situation rifle" one might keep in a vehicle for when the EDC isn't enough, it's nice to be able to have that magazine compatibility between the rifle and the sidearm. I believe cowboys used to do this. Makes a lot of sense. Bullets are weight that has to be carried.

If someone comes to my home, they'll be dealing with a lot more than just a pistol, and for the sake of opsec I'll leave it at that. ;)
