Looks like a Benchmark groovy frame to me.
Remember the name I looked for and it was Kapp groovy. Then the question is it a Kapp or a Benchmark? I think it's a Kapp ... or ??
Both made them. Maybe Benchmark made them for KAPP? I have one here and it takes a Benchmark safety. Just bought perhaps one of the last ones from PTP last week.
they're pretty comfy frames with those hogue grip panels.
