This is a basic thigh holster for an airsoft gun, it is simple to make, very durable, practical, and cheap.
Step 1: Materials
In order to make this thigh holder you will need
1. An airsoft pistol (dddduuuuuuuhhhh)
2. An adjustable belt (one without the holes, you need the ones for flag football)
3. A knife or a pair of scissors (with a point)
4. Vinyl basket (most dollar stores sell them for a dollar or two each)
Step 2: Cuts, This Way and That
You will need to cut out the entire bottom of the basket, this way the gun can fit through and it makes the holster ambidextrous. ( you could just cut out one half, but they work the same either way). You will also need to cut two slits about 1 inch apart on the front and back (in the middle area) so the belt can slip through.
Step 3: Slip It in Nice and Gentle Like
First, slip the belt in through the back slits (on the same side as the leg you are going to wear the holster on, you can always change it later. Then you need to put it on your leg and tie it through, then you will need to slip the extra through the slits on the front. Any excess belt can be slipped under the rest of the belt.
Step 4: Finish
And so that is what it looks like in the end.
You can also slip an extra mag behind the holster itself.
