Curious to see if anyone here has chronographed any .357 sig rounds out of their P2000 or USP Compact? Just wondering what people were getting and how much FPS were typically lost compared to a 4" barrel? I'm sure it's probably negligible but was just curious.

Very long delay in response, not sure if still relevant but friend and I did some 5 shot average testing back in the day on a Oehler:

Underwood 125gr fmj
P2000 1556fps
USPC 1545fps
P2000SK 1488fps
Steyr M357 1552fps
(current Underwood ammo showed to be a little slower last I checked, a reduction average of about 30fps but still the most power.

Sellier & Bellot 140gr fmj
P2000 1308fps
USPC 1296fps
P2000SK 1262fps
Steyr M357 1294fps

CorBon 115gr jhp
P2000 1485fps
USPC 1481fps
P2000SK 1443fps
Steyr M357 1494fps


All of the HKs we have tested seemed to have very good velocity for their barrel lengths (that goes for .357sig, .40, and 9mm)
We had thought that the chrono may be off, but we compared to many other guns and they are usually on top of the list when it comes to velocity by barrel length. Must be good chamber sealing and polygonal rifling.
Other guns that recorded high velocities for their barrel lengths were the Springfield EMP (.40 and 9mm), some Kahr K9 and K40, Steyr models, Glocks, some Kimber and some Para models in 9mm.

Someone else might be still be curious about this 2007 thread topic. But the original poster hasn't logged on since August 2014. Thanks for the update though...

I, for one, found the update to be extremely relevant to my interests. I just got into 357 Sig pretty heavily this summer, my three guns in the caliber are the USPc, 2000SK, and M357A1, and my favorite ammo so far is Underwood.

Good timing for me too! Just started on the .357 Sig about 4 months ago and love it! Got .357 Sig barrels for my Glock 23 and my Sig P239. Got all 3 calibers for both now, 9mm, .357Sig & .40. Now working on getting one in an HK P2000SK which I just bought the barrel. Not easy getting it in a .357 Sig so looking for a .40.

Well, I'm glad the post was appreciated. That was done back in the day when Underwood was new. It appears they have slightly lowered the heat on several calibers over the years but I'm not sure why because I have shot at least 30k rds of their ammo without issues.
I have done extensive testing when it comes to velocity and penetration and that goes for all the guns I own or have owned or have used.
Rifles included.

dsp, thats for providing the chronograph data on the 357 Sig from the P2000. I was wondering about the loss of velocity from the shorter barrel of the P2000, but your report puts those concerns to rest! The 357 Sig ballistics blow the 9mm out of the water by at least a coupe hundred feet per second!
Again, appreciate the data........
