yes, of course it is gun specific, make/model,carry mode
but most of us gun forum folks are not the proverbial "one and only one gun" guy, we carry and shoot a variety
not all that often that you will ever drop your gun while holstered, no matter your make/model, long/short, or carry mode... if it happens at all, very likely would happen during transitional events... obviously unrehearsed and unpredictable
dropped = "uncontrolled" by definition
life is not a movie, if you drop that HOT cup of coffee, let it fall (jump out of the way if you can)
if you drop that gun, let it fall
if ye must practice drop & catch, put a silver dollar on the back of your hand, "heads up", arm straight out, eyes closed
drop it and catch it before it hits the floor
see how many times you catch it heads up
if you catch it tails up, consider yourself shot with your own gun, by your own hand
(it's a little bit like dropping silver dollars into a metal waste can, instead of a one armed bandit in Vegas.. the best result you can realistically hope for is the same, but at least you won't hurt yourself)
