What's a Grip Index?
Justin Opinion introduces the 'Grip Index,' a metric to assess handgun fit by multiplying trigger reach by grip thickness. This index aims to provide a more comprehensive understanding of how a pistol will feel in hand compared to trigger reach alone. The video demonstrates the measurement process using calipers on various handguns, including the Sig Sauer P220, P227, and M&P Shield 45, highlighting how thickness significantly impacts the overall grip feel.
