I received and have shot my Taurus GX4. I am very surprised at how little recoil it has for such a small gun. I'm very impressed with it so far with only minimal rounds through it. Looking forward to putting it through its paces.
I also decided to go with a CYA holster with a wing attachment. It seems to do the job. Looking forward to training and learning with these new tools.
Sounds like you are well on your way. What brand of HP self defense ammo are you planning on? Have you considered, CCW Insurance yet?
