Great gun the PM9 is. It's my EDC. I just ordered a K5 myself today only I went with a hybrid kydex/ultrasuede. It was a little more pricey but I like the advantages of the kydex and the ultrasuede won't add much to the thickness according to the CS person I talked to (out of the other hybrid options). Also, it will help prevent any cracking of the kydex down the road and help keep the holster in my pocket when I draw.
