I recently saw a Sig 45, with night sights, which I was told was Mass Compliant. It seemed like a nice gun, and the reviews that I read were good. I think that it is made completely in the USA in New Hampshire. I much prefer purchasing guns, ammo, etc. made in the USA. I also like the decocker on a semi auto. Does anyone have any experience, or comments on these. If so, would appreciate hearing from you. Thanks
