Well in leu of Dougs project. I have bought a few things for my own G20 Hunting pistol.
I have a KKM 6'' barrel 5.5''and a Lone Wolf ported barrel. BOTH shot very well and the porting in the LW seems to work well with top loadings.
I am loading with Blue Dot and Longshot powders. I cast some bullets with a 200g TC Lyman mold and bought some 200g WFNGC bullets from Double Tap. Then I am also using Win 175g Silver tips and Hornady XTP 200 HP bullets.
Chronographed I have acheived over 1200 fps with both after market barrels with these powders with no pressure signes. Both of these barrels offer more support so NO smiles are present. I have hit 1300 + with the 175g from the 5.5 LW barrel.
I am staying with the std slide form the stock G20. I like the look. For leather, I have yet to receive either of what I have ordered. BUT both come with recomendations.
The first of a Leather chest rig from Double Diamond customs in Alaska.

I even took a 140# 3PT back in November with it!
