Got to shoot my early production P-10C on Tuesday at the 100 yard rifle range. I think a few weeks of getting shoot once or twice per week are finally paying off. I had fewer "bad" shots on Tuesday than I was having in January, even though I'm shooting a different pistol each week. So, for this range visit, the first target wound up being a sighter target, with all shots a little high and a little right. I went two clicks down for target 2 but hesitated to make a windage change. I got 19 of 20 on the paper with one just barely off to the right but with the elevation good now. Two good sub 6" groups on target 2. Rather than mess with the sight again, I decided to just hold a little left for target 3 and that worked just fine, except I held on average a little too far left. This comes down to eyesight at 100 yards with no magnification. I think I held more like a full bullseye left instead of 1/2 bull left, so I stacked up the hits on the left side of target 3 instead of just a little right on target 2. And my eyesight was getting bad so I threw a few shots. Here is the video...

I am also going to limit myself to 40 rounds, two targets of 20 rounds each, just to keep from wasting ammo as my eyesight gets strained. If all goes well on Thursday, I'll probably post another video on Friday. Then next Tuesday, I'll shoot the P-10F again. Finally.
A note on the P-10C's Primary Machine barrel that I bought in Wobbly's estate sale. My factory P-10C barrel was just sloppy at the chamber end, resulting in all kinds of vertical spread. Last year I shimmed the barrel and that fixed a lot of the vertical spread issues. But my shim was not a permanent solution, it was a test that I left in place, just like on the P-10S. I fully expected the shims to come loose or move, but they have been fine for hundreds of rounds in both guns. New Primary Machine C length match barrels were out of stock most of last year, so I jumped on the slightly used barrel Wobbly offered. It fit my P-10C just fine with no shims needed. That was a great change for my P-10C. I also have a PM barrel in the P-10F, but the factory barrel fit and performance was really good in that pistol anyway, so there wasn't much of an advantage of the PM barrel in that pistol. But I had almost quit shooting the P-10C altogether because it was so poor in lockup for what I needed at 100/200 yards. I am very happy with the P-10C now.
This is fun. This is not easy.
