i asked on here about iwb carry of my 4 inch barrel service six, i have decided to try it and need one last help on it. i am on a tight budget so i try to save when i can, so here is my question. i already have a couple pancake holsters, should i buy the straps to turn them into a iwb holster?, or get a complete iwb holster? the straps are $15 where a holster is $25-$50, thanks for your help.
