Most often I carry in Blade-Tech inside-the-belt (ITB) custom Kydex holsters, fitted with Tek-Lok clasps. I, also, frequently use Wm. Tucker's, 'HF-1' outside-the-belt; (OTB) and/or Matt Del Fatti's, 'BPB' inside-the-belt holsters.
The OTB holsters, that I use mostly at the range or during pistol matches, are Blade-Tech outside-the-belt custom Kydex holsters, once again fitted with Tek-Lok clasps; or else Blackhawk Serpa OTB paddle holsters which, while the Serpa design isn't all that concealable, is - once you learn how to use one properly - a very secure pistol platform.
