I've got over 15,000 draws from my Serpa with my Sig P229R. I use the trigger finger and I've never had a problem. I'll have to look into the ND thing some more. I prefer a leather mag pouch. I currently use a double from G&G, but just about every holster manufacturer makes them. The only time I've ever had difficulty drawing my pistol is when I have my belt way too loose. Your belt needs to be snug. I scored DG (distinguished grad) at Frontsight in the 4 day defensive handgun class with my Sig & Serpa combo, so it definitely didn't slow me down.
