While the ankle holster works for many people, the OP is going to carry a full-sized gun. I would hate to carry a 24 ounce gun (empty) that holds 17 9mm rounds on my ankle. I would probably break my other ankle getting into my truck!
Everyone has different needs, to be sure. My closest female friend - just a friend - carries a 4 1/4" barreled Ruger .357 revolver (I think it is a GP100 double action revolver that weighs 40 ounces empty) in an ankle holster. She is 5' 11" tall and weighs no more than 110 pounds. Her problem, as she described it to me was simple. She was so skinny and bony that there weren't a lot of places to hide her gun. And she refuses to change guns. Not that I can blame her - she shoots the center out of every target at up to 25 yards - so why change? Lately, however, she carries in a custom-built shoulder holster (vertical carry) and chooses to wear a jacket. The reason? She moved to Florida and finds that ankle-carry while wearing shorts is impractical.
Let's agree that today, we have an enormous variety of choices in holsters. Just 10 years ago, we were severely limited. Now, with such innovative designs as the Super Tuck (and its copies), we really have no excuse for not having a comfortable way to carry concealed.
Again, my advice to the OP is first to read the sticky thread on
What is the most popular Concealed Carry Holster?
And then, after doing this research, begin to narrow-down his choice. At least it is a good starting point. We can't collectively tell him that "this holster is best for you" because we aren't him.
And so it goes...
