One thing that I see over and over at the shows, is people trying to find a holster (especially an OWB holster) that they can just “clip on” and use, because they don’t like to wear a belt. I have to regretfully tell them that I don’t have a good concealment holster that does that, and the IWB’s that are clipped work better with a belt on, preferably a strong one.
Why is this? Well, it’s not too hard to figure out… guns have a good amount of mass and weight, even the smallish ones. The more mass and weight you hang on your pants, the more problematic they are going to be to control. A good belt not only helps to distribute that mass and weight around a bit more, but it helps to prevent unwanted movement, both of the holster and weapon, and of of the pants… 🙂
When I speak of a good, strong belt here, I’m not necessarily talking about specialty belts such as kydex reinforced belts, or specialized duty belts, although both are excellent for the job (although the duty belt might be a bit obvious). What you want to find, is one that doesn’t easily flex “up and down”, but will still wrap around you properly. Take a belt in your hand… place your thumb and index finger on the top edge and bottom edge of the belt, and try to push them together. If you can do this easily, this probably won’t make a good holster belt for you. If you can’t push them together easily, you probably will do OK.
Now, don’t rule out specialty belts such as kydex reinforced ones… those actually have some excellent points to them. The problem is, they may be more expensive than what you are willing to pay, and you may be able to get the same functionality out of a more traditional mens belt with a little shopping.
Be sure to apply the “squeeze test” liberally, though… my experience has been that most belts are more about fashion appeal than practical use now, and many of them are just not strong enough to actually help out in this situation.
Bear in mind, that these tips at most helpful when you are carrying waistline or below… IWB (Inside the waist), OWB (outside the waist), pocket holster (Yeah, it helps a little), and even ankle holster (keeps your pants in the right place). If you are carrying above the waist, such as a belly band, Packin’ Tee t-shirt, or a shoulder holster, then a strong belt system isn’t important for your carry ability, although it’s still not a bad idea in general.
