    I finally got around to getting some chrono results through my G26 with the 26 barrel, and the 19 barrel for comparison. These are 10 shot averages. I was a little surprised that the 124 +p short barrel was slower than the regular 124 +p, I expected the opposite. Also it is worth noting that the velocity loss for that 1/2 inch difference in barrel between the 26 and 19 barrel is roughly 50fps, this just confirms what has been written many times before.

    I would add that I found the short barrel ammo slightly(I mean slightly) more accurate overall between both barrels.


    G26 Barrel

    147gr Gold Dot - 995

    124gr +p short Barrel - 1113

    124 +p - 1130


    G19 Barrel

    147gr Gold Dot - 1045

    124gr +p short barrel - 1155

    124gr +p - 1189

    Thanks for this.

    Was it all Speer GD ammo?

    Good to know. I have the Gold Dot 147gr in my G26 right now but I'll be swapping them out for newly acquired Federal 115gr +P+ ammunition.

    Thanks for the results. Makes me even happier w/ the BlackHills 124gr+P I recently bought just for my G26. It runs 1220fps form two diff pistols.

    Most of the estimates I've heard have said 50fps lost per inch of barrel length. Your chrono results match my own from some time ago: about 50fps per half inch.

    Kinda hard to resist keeping the 4" barrel in the G26, ain't it? I had a G27 gun and G23 barrel combo at one time and it isn't as hard to hide an extra 1/2" of bare barrel as it is another 1/2" with a slide around it (and in the case of the G23 a longer frame and grip too).

    To all who have thanked me for the results.

    You're welcome. It was no problem, in fact it was my pleasure.

    Actually, since I tend to carry at 1 o'clock in the summer that 1/2 inch shorter barrel is a blessing when squatting or sitting. In the winter when I carry at 4 o'clock yes I will keep the 19 barrel in. The loss of 50 fps doesn't worry me, but there is no doubt that you have a better chance for expansion if only slight. I don't count on expansion, rather I consider it gravy. I do like the feel of the gun, and shot just a little beter with the G19 barrel installed, but I'm good either way.

    Thanks for the post. I have always figured the 26 did not require ammo specific for short barrels and your data bears that out.

    The 147 grain one is hot. I used to chrono it at around 978 fps with my G 17.

    That 50 FPS difference has been my experience as well--thanks for sharing.

    Yep, shot from my own & my buddy's G26s over an Oehler & CED chronographs. It definitely has more recoil impulse than other 9mm I have tried, closer to the feel of 357sig in my P239. Bullet expands well too in 2 layer denim covered wetpack.

    I'm guessing that the short barrel version burns so quick that the longer barrel is actually starting to slow the bullet down before it exits? Or the faster burning powder just has less oomph.

    I've read that the short barrel version is for 3" barrels and less. Your figures bear that out. It would be interesting to run this test with something with a true 3" barrel like an XD sub.

    Would also be interesting to see the difference in fps between the 124gr and 124+P. The 124gr seems to be easier to find in 50 rd boxes. I would only use it in a 4" barrel or longer though.

    Certainly worth a try if you can't find your favorite "latest/greatest" ammo. The XTP is old school, but still works fine, especially w/ a bit more vel behind it than Hornady loads. Price is right, accurate too.:supergrin:

    then compare that to the advertized velocities from speer's site.

    147gr 985fps (4" barrel)
    124+p SB 1150fps (3.5" barrel)
    124+p 1220 (4" barrel)

    assuming these are what the load needs to be in its velocity window, which ones are closest to advertized?

    hmmm :whistling:
