I was two lanes to your left with my son. I had my OD Saiga 308 for a muzzle break test, but we were shooting pistols for the most part due to the pistol line being full. Your rifle gave you away. We were wondering what that contraption was!
I put my recently acquired Sig P6/P225 up against my favorite P229 9mm to see how good the little surplus gun was. It's nice, it's a Sig, but...It's not in the same class as the P229. The 229 is just so much smoother, softer and more controllable in recoil.
