I don't care what kind of license you get, but having had a UT license since back when OK was only recognized by 4 states, and done the UT instructor bit for 3 years, I can answer your questions.
Advantages:
1. Backup license if primary lost or stolen.
2. Covers you is OK not renewed on time.
3. Cheap and easy to renew ($10 and a picture ea 5 years)
4. Remains valid regardless of where you live.
5. In the constantly changing list of state recognition, may/may not provide additional recognition.
6 The same is true of FL except FL is NOT cheap.
Possible Problems:
Mostly in your head. Much like the anti arguments against concealed carry: "well, what if....?"
If you run into that one exception of an OK LEO that does not know the SDA, you probably have more problems than the UT permit.
Who doesn't want to shoot?:
Lot of folks, especially many wives who don't want to have to go to the range with a bunch of us hairy-legged smart-offs.
A savvy gun owner wants his wife to have a CHL even if she never carries, if for no other reason so she is legal if he leaves a gun in the truck/car and she borrows it.
The logic is don't judge everyone by your circumstances.
Well, Rod, I guess you told me!
Most of your "advantages" wouldn't apply to the majority of us, albeit when they do apply, they would be helpful.
As far as problems being "in my head", aren't they all until they come to fruition? That one jakeleg LEO that you were talking about may just be the one looking for a reason to give you some real grief.
And, you've completely misunderstood my comment "Who doesn't want to shoot?". It was offered in the context of "Who doesn't like ice cream?" Or, why would anyone not want to shoot when taking a class?
I guess my real concern is that this is just another way to get around a law which has been beneficial for us, even though we wish the law was unnecessary.
