I only ankle carry when my family and I go to a local amusement park, and I'm riding rides, no upside down rides, just minimal stuff ..It's a Galco, with a velcro strap over the back of the hammer, and a calf support band. It has excellent retention....When I got it and tested it out (unloaded) I was doing jumping jacks, kicking my leg like a donkey in a ninja movie, and it stayed 100% completely secure....Any other time, I carry on my hip, but with it on the ankle it's only good for an incident that is occurring in your vicinity, and you can retrieve it, like if you heard shots ringing out near you... For very close quarters it's almost useless, even if I got down to it, by faking a heartattack or something, I'd still have to pull up my pant leg, and rip the velcro retention strap, and draw it from the tight neoprene holster part.....It's not the best choice, but if I want to have fun with my family as mentioned above...At least I have something if I need it, once we leave the park, It goes back on my hip.
