Small hijack

Expanding on AZAK's discussion, regarding the velocity loss between the G20 amd G29......I have both and have run identical loads across my chronograph from each gun.

The shorter barrel loses roughly 150 fps in typical loads.

Specifics... averages of ten round chronographed sets
Double Tap 200 gr XTP...............G20 - 1150 fps --- G29 - 994 fps
Double Tap 165 gr GD.................G20 - 1442 fps --- G29 - 1268 fps
180 gr HAP over 11.0 gr AA#7......G20 - 1217 fps --- G29 - 1072 fps

Just some added data for the discussion.
