The best holster you can carry is one that you actually use and one that will allow you to carry your weapon most effectively. Gladiusholsters.com was born to get the police officers back up gun off their ankle on onto their vest. An ankle holster is less tactical to draw from, difficult to run with, easy to loose while running, and becomes water logged when crossing creeks (something that happens often while chasing suspects). Recently I had a friend who was adamant about finding an ankle holster, and after expressing my reasons for disliking them he still wanted to find one. For his situation he felt very strongly about a holster on his ankle. The bottom line is with guns, tactics, and equipment it is a personal choice. Safety has a reasonably hard set of rules, but outside of safety there are many choices you can make for personal preference.
Inside the waistband holsters offer the best concealment, are easy to dress to, and are tactically advantageous in most positions. A kydex holster will hold its form when the weapon is drawn and allows for an unobstructed re-holster. Many leather and other soft holsters will not hold their form when the weapon is removed. I have found kydex to be the thinnest and most slim material to use for an inside the waistband holster. The thinner a holster is the easier it is to fit inside jeans, dress pants and other dress.
A kydex holster also offers a positive retention. This retention can be adjusted easily by the end user, and allows the user to have just the right amount based on what they are carrying. Kydex is a rigid plastic that protects the trigger and trigger well. I have seen leather holsters become soft in the area of the trigger and cause the weapon to fire while in the holster. While holstering in a soft material or a well-worn leather holster, I have seen the edge enter the trigger well and cause the weapon to discharge.
I am right handed and prefer to carry at the 3 or 4 o’clock position. Carrying in the low back becomes painful when riding in vehicles and is less accessible. The 1 o’clock or appendix carry will often dig into your body when sitting and requires a lot of adjustment to become comfortable to carry. The pro of the 1 o’clock position is that it is easy to draw from in many positions especially sitting in a vehicle. The weapon, its position, and the accessories (i.e. flashlight, extra mags) are all dependent on the activity I engage in.
Five years ago my movie theater package was a small .380 with 7 rounds. Today my movie theater setup is a full size pistol with a light and an extra mag (31 rounds). As situations change so does my style of carry and my weapon choice. I started with one weapon and one holster, so when choosing your holster for concealed carry choose the one that will allow you to carry your weapon most often. When a situation turns bad you want to have everything you need and nothing you don’t.
