Men, I want to update and replace my full size Sig Tac-op 1911 with a double stack 2011 with optic. I like a heavy gun due to recoil and a want to try a red dot as my eyes are not that good anymore. Just want an accurate straight-shooting gun I can shoot 5 to 20 yards with. What would the group recommend. May consider a striker fired but never shot/owned a poly or striker fire weapon.
