In the late 80's, I owned a HK P7M8-K3 (.380 with multicaliber conversion) that would routinely chronograph the old Federal HS (95 grain, IIRC) load at 1080-1100 fps. It was the "fastest" .380 firearm I've ever owned. Of course it was almost as large as a regular P7, but having the .32 ACP and .22 LR conversions were a lot of fun. Oddly, the .32 was the most accurate of the bunch.

After seeing the dismal velocity from a Seecamp, I don't carry a .380 anymore.
