Thanks guys. I might have thought of a strap or thumb break if I were going to use it fishing. But, my days of wading are gone. Mostly just hiking now. Also, there is quite a bit of retention in the back piece that molds around the cylinder, the trigger guard, and the bit that covers the cylinder in front. It does stay in the holster when held upside down, not that I would do handstands though. Thank you for the suggestion.
