Velocity Gains...

[matthewdanger]

I often see "increased velocity" as a benefit of the long slide models. I mostly just like the increased sight radius and better balance of my G35. While it is nice to know that I am getting a bit more velocity, I really don't think about it.

Is the increased velocity a big issue for you? Has anyone ever run some loads over a chrony to show the velocity gains when going from a G22 to a G35 or G24? Can someone post the velocity data?

Thanks!

9MM Chronograph Data

Glock 17, 1223 FPS (stock barrel)
Glock 27, 1158 FPS (KKM 9MM barrel)
Glock 35, 1283 FPS (KKM 9MM barrel)

All reloads same -
AA #7, 8.4 grains, Fed 100 primers, Montana Gold 121 IFP, 1.105"

For me it's only a factor in 9mm, and even then it's important to pick a bullet that will hold together.

Higher velocities will also help insure expansion in unusual applications, like extra clothing or other barriers.

I believe that the Speer Gold Dot 124 JHP +P load is probably the best for longslide 9mm's.

Another minor factor is reduced muzzle flash and blast.

IIRC, Butch did a chrony session with all sizes of 9's, maybe a search would dredge that up. It's been a while though.

Now that I think about it, his G-34 edged out his 17L for velocity. Butch speculated that it was because the 17L was older and had seen many more rounds through it.
