Can we draw the following hypothesis from the context (see options)?

Context:

A semi-automatic pistol is a type of pistol that is semiautomatic, meaning it uses the energy of the fired cartridge to cycle the action of the firearm and advance the next available cartridge into position for firing. One cartridge is fired each time the trigger of a semi-automatic pistol is pulled; the pistol's "disconnector" ensures this behavior.

Hypothesis: A semi-automatic pistol is available in different sizes.
Options are: -- Yes. -- It's impossible to say. -- No.
