My friend wanted to try his chrono, so he burned through a LOT of ammo, and this time I documented everything. All of this is from my personal Glock 29 SF using the stock barrel and my Lone Wolf 4.60" extended barrel. I know when I started with my 29, finding chrono data for the 29 was few and far between. Maybe this will help someone in the future. Note: only had 4 of the 220 HC and I was interested about the short barrel. So here are his notes he just emailed over.

As he or I try more, I will add them. Now that he has returned my gun, I'm going to clean this dirty "beach" lol
Yes velocities can be 60 to 100 fps less from the G-29 depending on the powder being used. Faster powders less differences in the shorter barrels.

Shadow, if you ever see one of the Lone Wolf 6" tubes for a 29 for sale, will you let me know?
I haven't seen any LWD 6" in quite some time, all my G-29 barrels are stock length. I am still looking to find a 357Sig 6.02 " conversion for the G-20...
If you dont want to save brass, they shoot from 9x25 barrels.

If you find something let me know, I'd like to have one too... for the G40.
Not sure why exactly, but I would like to have that setup, I carry a 357 Sig (G32)... so I'm calling the 6" conversion a worthwhile range toy I guess.

Ream it deeper, load them long! But hey, if you're handloading, why limit yourself with the 357 sig. As I said you can shoot both from the 9x25 barrel. That's a 9x23 vs 9x25
I have the 6.02" 9x25 barrel for the G-20 already just wanting a 357Sig to add to the collection.
Also have 357 Sig and 9x25 conversions in stock length for the G-29 8)
Thanks for the numbers!
I carry a G29 and have always felt the Hornady Custom 155 was a hot load, it's also one I carry often.
Are those new lots of UW ammo? Specifically the 200 XTP's?

Yes, but I found no difference in the old brass cases XTPs and the newer nickel cased stuff.

About a year ago I purchased some 200 XTP's and some FMJ's then a few months later ordered some more. The 200 gr loads purchased later felt much softer, had a noticeable reduction in report and almost no flash. All of this was very unlike my first experience with 200 gr UW loads which were loud, snappy, had lots of flash and left me bruised and sore. I've only ever experienced the Nickel case loadings but from what I understand they changed powders and this was the reason for my experience (explanation from Underwood).
I have seen several youtube vids of the 200 XTP's shooting much slower than they once did with earlier videos so to see 1163 and 1244 I was a bit surprised.
@Jason B
One thing to note for the 1244, is this was a Lonewolf barrel. I've noticed that aftermarket barrels tend to produce higher speeds than Glock barrels.
How many shots per round for those averages?
Fenix 180gr Gold Dot
Glock 29- 3.77" - 1276 fps
4.6" Lone Wolf - 1328 fps
Glock 40 - 1361 fps
Impressive being right on par with the UW loads you tested earlier!
Was at my uncles place and fired a few Underwood 165 GD over his chrono. "WOW" is all I can say, just wow !
Underwood 165 Gold Dot
3.78 - 1337 & 655
4.60 - 1441 & 761
Then he shot the Doubletap and Underwood 200 HC
DoubleTap 200 Hardcast
3.78" - 1077 & 515
4.60" - 1181 & 619
Underwood 200 Hardcast
3.78" - 1159 & 596
4.60" - 1246 & 689
