By very definition, semi-automatic pistols all have some basic features and functions in common. What makes them "semi-automatic" is the recoil system that performs a carefully orchestrated process of:
- Moving the slide to the rear.
- Ejecting the spent cartridge case.
- Cocking the hammer or striker for the next shot.
- Moving forward and stripping a fresh cartridge from the magazine.
- Loading that cartridge into the chamber as the slide closes and locks into position.
