I tested the velocities out of a Roni G2-10 10mm Glock 20 with a 16 inch barrel versus a Glock G20. I used a chronograph and tested two rounds each of Civil Defense 60gr, Underwood Xtreme Defender 115gr and Barnes VorTX 155 gr. There was a huge increase in the Civil Defense and a moderate increase in the Xtreme Defender. Marginal in the Barnes.
