Got it. Took it to the range hoping the hype was worth it. The Sig Sauer M320 M18 is glorious. My son looked like he had done some special forces training. Sorry Springfield XDM40 you've just been replaced as my go to.

I got my M18 three days after ordering. I was impressed as it handled well had a smooth trigger. As you can see, I put on a Mirzon grip module and added a red dot, and light. I am very pleased with Bud’s and very pleased with my weapon. It is the ultimate home defense pistol.
