Ready to buy a tuckable for my 23. Looking at the Crossbreed SuperTuck and the American Holster InvisiTuck. Pros/Cons to Leather vs Kydex? Big question is retention of the leather after a few years. Will it be like my pancake holster for my Ruger SP101 and be just as good, perhaps better, after it shapes to my side? Sorry if this is a common question. Tried to look through the archives, but didn't see what I wanted..
