Wheel Man:
Get a piece of heavy bootlace and take off your belt.
Loop the lace around the belt and then tie it off with a good knot.
Lay the (UNLOADED) pistol behind the belt and loop the lace loosely around the back of it and then back around the belt. Tie off the second loop going around the belt.
You know have a length of lace with a loop on each end that will fit the belt. Cut off any extra lace.
Put your belt back on, and in the process thread it through the two belt loops. Leave them about 3 to 4 inches apart. Left side, right side - anywhere. It doesn’t matter. Do this with the larger loop between the two belt loops pointing up.
Slip the pistol inside the lace between the two belt loops and then inside the pants. The pistol will not slide down your leg because it’s restrained by the larger lace loop. When you are not carrying, slide the two belt loops together and the lace itself inside your waistband so it doesn’t show.
This whole outfit, called a “shoestring holster†will work well until you get your regular holster - and you may like it enough to use it afterwards. Be aware though, that it may set you back $2.00 or so - cash money.
O.K., the tactical types can laugh if they want too. But this simple idea works with mid and full sized pistols but not so well with revolvers. I assure you that the person that taught me this trick was no amateur.
