If you appendix carry with one, you can really impress the ladies!!Its the cool factor baby. I own a couple and have used them, once. Yep count it out, once. You know how heavy those dang things are loaded? In a 18 with the rounds flying out rapidly total fun factor. In a 17 dumping it one round at a time that sucker is just a pain. But hey I got my cool 33 round mags for bragging purposes.
