I've used many holsters over the years. When I first tried out the Safariland Custom Fit paddle, I knew that I wouldn't be using any of my other holsters again.
I've had mine comming on two years. It is comfortable, and retains my pistol very well with the added bonus of giving a smooth draw.
The only problem I have with it is that there is a small plastic disk that provides tension against the firearm. This little disk rubbed a 2" mark off my pistol's finish.
