George Zimmerman -- I Can Get My Guns Back ... And My Chewing Gum!

George Zimmerman can finally be reunited with the arsenal of guns and ammo that was recently seized from his home, since he's no longer facing domestic violence charges ... officials tell TMZ.

The Seminole County Sheriff's office confirmed ... the case against Zimmerman was just dropped after his GF Samantha Scheibe backed off her story that George got violent with her back in November.

And no charges, means no reason for cops to keep the guns (and chewing gum) that were seized from his home following the initial alleged incident ... a cache that includes 3 handguns, a semiautomatic rifle and the shotgun that Scheibe had claimed Zimmerman used to threaten her.

Here's the entire list of items seized:

• 3 Black Handgun Holsters
• 1 Pack of Gum
• 1 Religious Pendant
• 1 Flashlight
• 1 Pocket Knife
• 1 Sanitizing Wipe
• 2 cell phones
• 2 .223 rounds
• 8 9mm rounds
• 2 .40 caliber magazines with 8 rounds each
• 2 9mm magazines ( 1 with 14 rounds and 1 with 15 rounds )
• 1 Interarms .380 Handgun
• 2 Taurus 9mm Handgun
• 1 Glock 19 handgun
• 1 Kel-Tec 12 Gauge shotgun
• 13 12 Gauge Shotgun rounds
• 1 AR15 rifle
• 1 Soft Sided gun case
• 2 AR15 magazines
• 59 AR15 Rounds
• 1 Combination Lock

We're told George is now free to pick up his stuff whenever he wants -- but so far, he has NOT come by the station.
