Anything in leather. Kydex sucks but that's just me and YMMV.
I have a Bravo Concealment BCA for my G 17, I highly recommend it!
Two questions: how do you dress and how concealed? If you are a fiftysomething male and dressed casually it's pretty easy. Are usually carry with a Blackhawk OWB.I also have a crossbreed supertuck for more concealed.
Can you conceal that well with that holster?
