Rick Scott Approves Bill to "Briefly" Flash Your Gun at People
By Matthew Hendley Mon., Jun. 20 2011 at 11:20 AM

Florida doesn't have an open-carry law to show your piece off in public, but it's now OK to "briefly and openly" flash your firearm to the populace.

Since Gov. Rick Scott signed SB 234 into law Friday, it's been legal to show off your hardware -- but just for a little bit.

Here's the addition to Florida Statutes that bans openly carrying your weaponry:

It is not a violation of this section for a person licensed to carry a concealed firearm as provided in s. 790.06(1), and who is lawfully carrying a firearm in a concealed manner, to briefly and openly display the firearm to the ordinary sight of another person, unless the firearm is intentionally displayed in an angry or threatening manner, not in necessary self-defense.

While I usually carry a snub nosed .38 in a pocket holster in my pants, I occasionally carry a revolver in an inside the waist band holster under a jacket in the Florida winter. I have had a gust of wind blow my jacket back and prior to the passage of this law, I might have had problems with the authorities if someone in the parking lot would have noticed.
