Algodoo

A 9mm SAO P226

This has a few features.

One of them is a decocker right above the mag release. To operate it, grab the
switch at the top, and pull it downward slowly.

Heres a video of the function

Above the gun are warning symbols saying what the gun needs to have in order to fire.
The left-most one is saying the gun needs a magazine, the middle one says you need
to chamber a round to fire, and the last one is, the hammer needs to be cocked.

Enter to fire
Down for slide release
M for mag release
