I started carrying concealed around 2006 and like most people at that time I purchased a nice leather inside the waistband holster for my gun.
At first I was dedicated to carrying every single day. But within 2 weeks I remember waking up, looking at my gun, and deciding to leave it in the safe because I didn't feel like carrying it.
The novelty wore off quickly and the reality of discomfort had set in.
In my search to find something more comfortable I purchased a custom made kydex holster. This made sense to me because the kydex material was thinner than the leather and light weight.
What I didn't factor in was that it was hard as a rock and it ended up no more comfortable than the leather IWB holster.
Again my gun was left in the safe more days than it was carried.
