Random airsoft trick I figured out.

Found a trick to fit an extra shot into my airsoft gun.

1 - Fill mag (12 pellets or whatever they're called, in my case.)
2 - Pull back on (slide? The part that you pull on before you shoot.)
3 - Eject mag.
4 - Put another in the mag (refill back to 12)
5 - Get 13 shots! :-)
