The way that statute is worded, it looks like Mexican Carry would be legal without a permit. It's obvious from the grip that it's a gun, so it's not concealed, right?
Mexican carry is debateable, because of how "ordinary observation" is interpreted? A trained cop might be able to tell you're carrying with the slightest indication of the weapon printing through your shirt. Is your weapon concealed to him
since he can discern what you have with ordinary observation? Or, since most sheeple are so oblivious anyway, does your gun grip look too much like a cell phone to them?
Plus, carrying this way without a CC permit exposes you to unnecessary risk of prosecution. I thought the risk of becoming a "criminal" by accidentally covering my OC weapon, say with a coat, etc, was so high, it was the #1 reason I decided to get my CC permit.
Just splitting hairs here, but my point is you never know how LE or a judge will enforce/interpret the law when it comes to undefined terms, like "ordinary observation".
