I just finished testing some WWB 230gr JHP in Vyse gel. Four rounds in a full size 1911, two through heavy clothing and two in bare gel. I also shot two rounds with a 3-inch Defender in bare gel. While two rounds in bare gel isn't a large sample size it performed better then I thought it would from a 3-inch barrel.

I also did the same test with some Underwood 200gr +P bonded JHP (Gold Dot). In both Vyse organic gel as well as Clear gel.

The extra velocity and recoil and the +P didn't seem to help at all and limited penetration.
