.357 SIG velocity from Glock 24 length barrel??

[JMHalverson]

I use a Glock 35 with .357 SIG KKM conversion barrel as a duty pistol and our issue Speer 125 gr. ammunition is going at just about 1550 fps. Anyone got any idea what the velocity is out of the 6" Glock 24 length barrel that KKM offers?

1600-1650 FPS.
I like my KKM barrel.

I would say that if you use the Double Tap load from your standard barrel in your 35 that you will see closer to 1700fps without going to the slightly longer barrel. I am getting around 1600fps with the 125gr Gold Dots from Double Tap from a Glock 31 4.5" barrel and with little to no flash.

Recoil is about the same. The Gold Dots I had left from CCI put on one hell of a light show.
