Jim - update to your much appreciated help. Came back to Alaska with a full double shoulder and got to work. The slide, with a minor modification, came out rather well. I did not get a snap set. Due to the remoteness of my post I made do with what I had. The holster- thanks to your tutorial- came out better than expected. I mis-measured something because, while my pistol fits, it is a forced tight squeeze. Pics of the second attempt to follow. Thanks, again.
Mike
