I took my new P30 out this morning for her initial firing after wiping off the packing grease and applying some Miltech-1 along the slide rails for lubrication. I was only shooting for function today, so I didn't take any targets. I was just shooting into the back berm. I was shooting some old ammo that I have had on hand for several years:
50 rounds of 115 grain FMJ hand loads. The label stated they were loaded with 6.1 grains of Unique.
5 rounds of loose JHPs with the cases marked "RP" and "+P".
20 rounds of Federal 124 grain Hydra-Shok HP (P9HS1)
30 rounds of Federal 124 grain Hydra-Shok HP (P9HS1G)*
I had one failure to fire with the first magazine of these due to operator error. I had failed to seat the magazine fully and as a result it failed to chamber a round when I racked the slide.
14 rounds of 124 grain Speer Gold Dot JHP +P
After the 14th shot, I noticed the rear sight had drifted to the right. When I checked this I found I could easily slide the sight back and forth with my fingers.
I guess I'll be calling HK on Monday...
* What is the difference between P9HS1 and 9HS1G?
