I got the Colt Competition series 80. I see they are now offered in series 70. Main reason for me going with the Colt was the undercut of the grip and trigger guard. I don’t care for the Novak style rear sight but it works. Didn’t put too much money in the gun and got rid of the series 80 parts. Extended firing pin, Dawson mag well, full length guide rod, 11lb recoil spring, 17lb main spring, aluminum shock buff, grip tape on front strap is all I addeand tweaked the sear spring. Works fine for a fun gun.
Wanted a STI DVC Classic but too expensive for me as a play gun.
Other one I would consider is the SA Range Officer as I like the rear sight.
