I use CrossBreed Minitucks for 9 through 45 in Kahrs. I bought my first Hybrid Kydex/horse-leather Mini Tuck for my PM9. It works for the P9, K9, P40, and PM45, and finally the P45. I use a sturdy Kydex-reinforced leather gun belt by Looper for carry and belt tightness is key to retention. The 45's did stretch the holster a bit, but the leather allows larger pistols while the Kydex grips the pistols. A Kydex holster won't give, so mods/heat are usually required.
Length of the barrel/slide isn't a problem because the Mini Tucks are open, not closed on the bottom.
My P380 rides in its own Mini Tuck, but I didn't get the horse hide for it, darn it.
