I got my Compact scope parallax info from both the '85 and '90 catalog. Right except for the 2.5x20 and 4X rimfire. Dug out my 2.5X scope box. Has "100yds set parallax" on it. Anyway,I Binged this info that is supposedly from Leupolds "Answer Guide" although try as I did I couldn't confirm it:
From the Leupold.com Answer Guide,
Our scopes are set to be parallax free at the following yardages:
Handgun scopes - 100 yards
