Two adjustment knobs are used to secure the base to the receiver. A bore-sighting device is usually used to roughly zero the sight before a first-time shooter takes it to the range.

The Chiappa Rhino is an example of a pistol with a low bore axis. The SIG Sauer P226 is an example of a pistol with a high bore axis.. The recoil from a fired cartridge (and the action movement) exerts a rearward impulse along the bore axis, which is commonly above the center of mass of the gun.

The P226 was the runner-up to the M9, as both were the only two to satisfactorily pass the trials. However, the P226 would ultimately not be chosen. In a later competition for a compact service pistol, SIG Sauer's P228 became the M11 ...
