Interesting gun lock

[Dan Shapiro]

You can set the combination between 2 and 9 digits. No need for a marked dial with numbers. If your combination is 2-4-2, you roll the dial 2 clicks (in either direction), then back 4 clicks, then forward 2 OR MORE clicks. Pull back your slide, the gun lock ejects and chambers a round. Since it's 'electronic", you can set it to OPEN the gun lock when the battery fails, or remain locked until you change the battery. Either way, an alarm goes off when the battery gets low.

I could never remember my combination lock numbers for my locker in school. For my home safe with electronic lock I wrote the numbers on sticky pads and placed them in several locations. Now I need to find those sticky notes. 8-/
