So I just ordered a Mark23 and I was looking at hkparts.net for the thread protectors. Is the one they carry a factory HK part? Does anyone make a good holster for the gun? All I have seen was Blade Tech and Kramer. I would prefer a leather holster if possible, vertical scabbard or IWB. Yeah I know it's a big ass pistol... I'm trying to make it some-what practical.
