Default Glock G30/G36 Chrono Data?

Does anyone have any accurate Chrono Data for both standard pressure and "+P" factory loads for the 3.8 in. barreled .45 ACP Glocks? Ammo manufactures test barrels are generally 5.0 in., and I was wondering what both the velocity drop and "+P" increase actually represented in these shorter, octagonal-rifled barrels.

Thanks.

I did some testing with RA45TP in my G30SF a while back. I always test other known velocity loads with new tests, and everything was on par with previous testing & published data. Here's a link to my thread:

Glock 30SF (3.78" Barrel)
RA45TP
Winchester Ranger T 230gr +P
Advertised Velocity: 990fps from a 5" Test Barrel


927fps
887fps
918fps
896fps
909fps
917fps
918fps
909fps
916fps
892fps

Average: 909fps
ES: 40

Thank you for this. I'm no engineer, but it seems the loss is insignificant.

Thanks you.

I noticed that your test was several years ago. Any plans to expand the selections? Was looking for a Winchester series with maybe the WWB and PDX1, or a Federal series with AE, HST, and HST+P.

As popular as these pistols are, I am surprised that there is not more chrono data available.

I don't have the exact numbers on hand but when I chronoed my G30SF with 230gr Federal HST, it was only ~50fps less than with my G21SF. It made me trust my G30SF even more.
