I am pondering over whether to get a CTAK or MTAK for my PM9. I want a good, tuckable, holster with an established reputation. Correspondance with the company (they return emails very quickly), indicates that the leather adds about an1/8" in total thickness. I wear an undershirt year around, but wondered if any found a preference between leather and the kydex in terms of comfort. I tend to perspire alot at all times. The leather would aborb the moisture. The kydex would repell it. Either way, I would expect a damp spot where the holster sits. I can live with it. This will be my first CC holster. The Mtak looks abit bulkier with more surface to body contact area. Also, any expereince with the differant types of clips. J clip, regular, v clip, etc... ? I want them as unobtrusive as possible, but still affording the support... Any input would be welcome. Thanks!
