I've got 2 9mms, and have a 9mm conversion barrel on backorder for my P229.
I have two Tauri in 9mm, because one was my first pistol, and it's fullsize, and the 9mm, IMO, was the best combination of defensive capabilities and cost.
I bought the second (PT111) at it's compact for when I get my CCW.
I'm ordering the 9mm conversion barrel for the P229 because .40 is that much more expensive to shoot.
So, three total.
I also have a ruger 10/22 and walther p-22, both in .22LR.
Only one in the rest.
