What velocities do you get with HV and SV ammo? How much is this reduced compared to unported barrels? Thanks.

It varies some from integral to integral based on the location and size of the porting. With CCI Minimag I get a about 1000 fps from the Phoenix and SRT Integral. In a pistol with no porting I got a little over 1120 fps so the difference is about 120-150 fps. The Siris runs about 100 fps less so it likely has more aggressive porting or a shorter barrel. I have not chrono'd the suppressed High Standard yet. For the SV, the difference between the integral and no can is 50 fps to 100 fps -- the integrally suppressed V for the first two is around 875fps to 900 fps while the Siris runs about 800 fps.
