I shot my favorite IDPA handload over a chronograph yesterday and got some interesting results. The Glock 26 (3.5" barrel) average was 63.5 fps lower than my Glock 17 (4.5" barrel) with my handload. The G26 average was 1003.6 fps, and the G17 average was 1067.1 fps. Handload: Federal cases CCI small pistol primer Berry's 124 grain flat point bullet 4.0 grains of Bullseye powder 1.050" OAL I knew there would be a difference with the 1" shorter barrel. Just thought it was interesting. Now I need to test some other rounds just for grins.
