K'nex Colt .25

About: If you want to add me on XBOX Live, my Gamertag is D1rty Di3sel. BUT, along with the friend request, send a text or voice message that states your Instructables user name.

I believe this is the first, if not one of the first K'nex Saturday Night Specials.  Another name for this gun would be The Nano TDS.  Also, I'm not sure if this would meet the definition of a true trigger, so I won't say it is.  Constructive criticism is welcome.  However, I WILL NOT tolerate spam or profanity, regardless of whether it is directed toward me or someone else.

Range is surprising for its size
Decent Tertiary Weapon (Backup gun to your backup gun)
Easily concealed

5-round mag
Slow to reload
6 modded pieces (However, 4 are optional)

Well, what are you waiting for, build it!

    I have to say, I do rather like small pistols like this that manage to come up with something new, so well done! Funnily enough, I came up with something similar to this before viewing this instructable when trying to make the smallest true trigger with a mag. I'll try uploading it when i figure out how to...I'm terrible with computers.

    Not overly impressive but at least you thought up a very nice new trigger for it.
    (also, you won't tolerate profanity, but look at your username :P)

    Look up "Profanity" on wikipedia and then click on the directory link "Severity," it has statistics on what americans think are and are not profanity, I would post a link but my comment would problably be flagged into oblivion if I did.

    ya, I agree with DJ Radio. Since when is the word "crap" considered to be included in the modern day vulgar language list? Anyways decent sidearm 3*.

    People might not find it too impressive but hey it's still cute. It's a simple weapon that you'd be able to build quickly and keep in your pocket if you're afraid of being attacked by ninja monkeys on the way to school or something.
