Hello everyone. I currently have a pretty crappy TDI-SVG Short Vertical Grip. It looks like an MP5's grip. Its way too short. I am looking for a new grip that WILL fit my Samco M33s. The rails on the 33 is much different than the standard rails on a flat-top. I was wondering if I should get a grip that is molded for fingers, or just get a regular grip similar to the KAC? Please remember I need something that will fit these unusual rails. Thanks for your help.
