I've been searching for an IWB holster for my Glock 43X with an optic. Tried two Kydex holsters that didn't feel comfortable. This by far is the best IWB holster for me. At the 4 o'clock position on my right side. I know it's there but not as noticeable as the Kydex ones. I'd recommend this to anyone having difficulty in finding a comfortable holster.
