    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.

    Not as much difference as I thought. I wonder how popular factory loads stand up?

    I don't load for 9mm, just for .45 and .38 in pistol. The results above are consistent my my chrono testing of a 17 and a 26.

    In the 2000 Glock annual Ed Siemon tested the same ammo in a 34, a 19, and a 26. The difference was typically about 70 fps drop from 34 to 19, and another 50 or so from 19 to 26.

    I had a chance to chronograph some factory 124 grain Speer +P Gold Dots this afternoon.

    Glock 17 avg.: 1240 fps
    Glock 26 avg.: 1165 fps
    Difference: 75 fps

    Although the sample was relatively small, the data is consistent with other tests I've done in the past.

    Thanks Shane that sounds about right. The Gold Dot is a great round.
