Well, I tried using the 4 that I have that I purchased off of a friend and frankly, they're terrible. Either I have a hard time taking the mag out quickly, or I catch it, or it about falls out of my hand, or.......... What do you folks use for competition. Mind you, I'm just trying to have fun and not trying to beat Sevigny, so am looking for good products but not really expensive one if possible. Thanks.... By the way the Blade-tech DOH holster recommended came and I've tried it out. NICE... Thank you all for that recommendation.
