I recently purchased a 1938 S/42 shooter Luger. When The gun arrived I put 50 rounds through it. The gun performed well other than two failure to feed (FTF?). Here is a photo of the target. I was shooting at 15 yards two handed using Winchester 115gr.
The shooting may not be as good as others here can do but it is some of the best I have done.
Here is a photo of the normal pattern that I usually get at the same distance with my Ruger Mark II target pistol using whatever 22 ammo was on sale.
I think it is time to try different brands of ammo in the Ruger.
Thanks,
Chris
