Stamp is in and I am SBR'ing a SIG MPX pistol for use in PCC, general shooting, etc. I am asking those with extensive experience with SBR length weapons about Vertical Foregrips. Is there value in using a VFG on a SBR for control and to keep support hand away from the muzzle? The Sig MPX pistol comes with a removable piece on the bottom rail to help prevent support sliding forward also.
