I have used Blade Tech, Side Armour and SafariLand for my N frames in USPSA and Steel Challenge competition but the absolute best I can recommend is the Double Alpha Race Master. I had a small issue when I first bought mine and Saul Kirsch, the owner in the Netherlands, answered my question and resolved the issue in less than 12 hours! First class product and service. Accept no substitutes.
