First I want to tell you that I own 4 Vedder holsters all of which are IWB, LightTuck for my M&P Shield plus and Sig 365X and RapidTuck for my M&P 40 Compact and Sig 365 X. The LightTuck works great and is comfortable especially if wearing a T-shirt but you do feel it being hard Kydex material. I wanted a IWB holster for my 40 compact that was comfortable and because of the size and thickness of the pistol I thought I'd try the RapidTuck being that it's a hybrid of Leather and Kydex. This holster is the most comfortable holster out of the many I've purchased. I liked it so much I wanted to try it with my tiny Sig 365 X to see how well it would work and it feels just as great with a smaller pistol as well. I will be outfitting all of my carry pistols with the RapidTuck.
