I have several stun guns (9mm) as TS calls them, a couple .40's and a couple .45's - wish I had NEVER bought a 380. It's like the redheaded stepchild that rarely gets fed. Several of my friends have the G43 and love it. A couple carry the Shield and really like it as well. Guess my thoughts are to stick with 9mm if you have other 9mm guns. 380 ammo is overpriced in my neck of the woods, anyway.
By the way...all my buddies got a decent little discount with the Glock blue label program. Not sure if that might persuade you. It knocked $100 off the purchase price.
