Kodiak is right on about Honduras.. several years back I looked into setting up a business there after retirement.
Gun laws are very liberal, however it is pretty much a chaste system, there are the wealthy and the dirt poor. Also you can own a gun, you can carry a gun, you can carry anything you want.
Permits (own or carry) are $450 US and are good for 10 years, with them you can buy Full auto, short barreled, what ever you want. I had a friend who carried a 20 ga Stevens Double sawed off in his briefcase.
However, "La Mordita" (the payoff) is alive and well, screw up and assault someone, or get into it with the wrong persons punk kid, and your screwed. Saw it happen to a buddy's partner in a business on the beach. Local well off kid came in a tried to steal from him, a fist fight ensued, his partner lost his visa and had to leave the country. God help him if he had shot him.. I hear the prisons there really suck.
Prices are not bad, heck when a Bottle coke here was a buck, same there was .33 cents, REAL Heineken .06% alcohol not avalable in US were only a buck, and that was convenience store prices. Americans can own property, carry guns, no income tax (12% fed sales tax), GREAT weather, all kinds of nice stuff. However Island Life ain't for everyone. There are a large number of ex-pats living on Roatan, Utila, Guanja, and on the mainland. It is beautiful. Problem is on the islands, really no place to shoot at anything over about 25yds. On the Mainland, whole different story, but crime much higher there.
However, I believe I will take my chances right here in The Republic of Texas... and Yes the Right to Succeed from the Union is in the Statehood Agreement, and within our (Texas) Constitution.
