The gun on the left of page 3 is a 1911-A1 or later with a spur hammer, ambidextrous safety switch, extended beavertail to prevent hammer bite, checkered grip, and what looks to be a ported compensator with the frame shortened to... err... compensate for its added length? Also a nice rear sight. The gun on the right appears to be a factory standard Glock of some variety, but without more detail, the caliber is anyone's guess.
