Last cruise to the carib/central america [5 years ago] there were 2 I recall uniformed officers with revolvers ,many uniformed private guards had what looked like model 10's and a plain clothes excursion guard had a J frame . Going from Haiti to Dominican rep. was night and day [revolvers vs HK and glocks ] , you behaved yourself in italian airports they were bad ass gun carrying dudes , serbian were AK packing but rather very relaxed and glocked up , i was grateful him pointing out the minefields were cleared out years ago some miles away .
