I have found that the Safariland 5186 will do it all for me. The 5181 is also a good choice and gives added protection with the wings that function perfectly.
The hosters are lined, and create little wear to the finish, they draw smooth and fast, muzzle exits at bottom of belt, IDPA legal and I can run like heck RO'ing and not worry about it.
Best part.... My draw is the same for USPSA, IDPA, carry.. anything. That makes it the fastest, surest draw for me. I leave a 5186 on my CR Speed belt, and use a 5186 or 5181 for carry depending on if I want a paddle or not.
