As noted previously, I started out using AIWB carry nearly 30 years ago and have gone through a LOT of holsters. I currently primarily use the superb JM Custom AIWB holster with extra tuck and solid belt loop to carry a 9 mm Glock or M&P AIWB each day, including bicycling to and from work. Whenever possible, I prefer to have a light on my pistol; so far the inability to easily have a light on my pistol has been one of the drawbacks to AIWB carry. Fortunately Tony Mayer at JM Custom solved that problem when he fabricated an AIWB holster that allows me to carry a G19 with x300U light installed. The draw is just as quick as with my standard JM custom AIWB. Last week I had to drive several hours to an all day meeting and then several more hours back home, all while wearing suit and was perfectly comfortable wearing my new JM Custom AIWB holster.
