Similar experience on durability. Have one (for "Practice" and local matches) with over 20K+. It is currently set up with Apex trigger, tungsten weights glued into the cavity inside the back strap, Vortex Venom and Streamlight tlr-1. I believe it weighs 35+1 oz unloaded when using Henning's +3 basepads.
The "match gun" has 12K+. It's set up with Apex Trigger, TLR1 and CMore RTS2. It also has the Brass backstrap from Taylor Freelance and that gets the weight to 38+ oz.(Almost as much as a SP01)
I run 135 grain coated bullets.
