I had my first outing at the range to use my new Garmin Xero C1 Pro chronograph. One of the tests I wanted to do was the Federal 9mm HST 124 gr +P ammo that I use in two different pocket guns, the Kahr PM9 and the S&W 940-1. I wanted to see what the velocity would be in these short-barrel guns, and what kind of velocity loss there might be in the revolver with the barrel/cylinder gap versus the semi-auto. I was surprised by the results.
Here's the five-shot results for the Kahr PM9, with the stated 3.1" barrel:
Anyway, there's the outcome. I was happy to see that the little guns still are packing a pretty good punch.
