firearm and undershirt

The Wonders of an Undershirt

When I first started carrying, I prioritized holsters that were comfortable to carry. I carried strong side pseudo-appendix at the time, around 2 o’clock, and I gravitated towards holsters that were more comfortable. I found my perfect holster in Black Arch and the Protos was a my every day wear for three or four years, until I made the move to a weapon light, which forced a change. While I love Black Arch holsters, they don’t support lights on any of their holsters. I never bothered to wear an undershirt because my holster was so comfortable.

As I started to look at holsters that would fit the guns I carry (CZ P-07, HK P30, G19 MOS), with the exception of the 19, finding a holster supporting a light forced me down the full kydex route: getting a leather backed holster simply wasn’t an option. As I tried out the new kydex holsters, and started to experiment with actual appendix carry, I quickly realized that having a kydex holster against my bare skin was not just less than ideal, it was a non-starter for me.

I started to experiment with different ways to make carrying a kydex holster more comfortable, and I found that an undershirt made a huge difference.

An Undershirt is for More Than Just Comfort

An unintended consequence of wearing an undershirt was that it actually made my draw better, I found I could get a better grip on my gun, since my hand wasn’t competing with my own skin to get a grip and get the gun out. Previously, I found I would tear up my thumb on the holster backing, before developing a callus, or have the uncomfortable drag of my thumb against my bare skin. Having an undershirt, especially the synthetic ones, made drawing easier. I also found that when training, either live or dry fire, that the synthetic shirts stay in place better than the cotton a shirts. Synthetic undershirts also don’t bunch up, making re-holstering much safer. I ultimately settled on synthetic shirts for both every day carry and training.

Synthetic vs Cotton

Initially I experimented with cotton undershirts, but found they did not work well for what I needed. First, they did not stay in place well. If I adjusted my pants, practiced my draw, or even got out of the car, the undershirt didn’t stay in place. While this wasn’t great for comfort, it was horrible for safety. The cotton undershirts would bunch up, making re-holstering downright dangerous. Finding the great cotton undershirt experiment a failure, I tried synthetic undershirts and found them to be much better. They stayed in place, never bunched up or caused a dangerous situation with the trigger guard, and had the added benefit of being cooler than their cotton counterparts. I suspect they will need to be rotated more frequently due to the wear from the grip on the synthetic material, but overall, I find them a much better fit than the classic cotton beater.

I wish I’d made the move to wearing undershirts sooner. I think I would have branched out into other carry methods, holsters, and guns sooner had I not felt tied down to trying to carry with a “comfortable” holster.
