Polished the feedramp and took a couple coils off the recoil spring. (36lb).
Ran 5 mags through it with 115 and 124gr. Likes either round no jams.
Seems good now.

Nicely done. Lot of good info here.

Congrats on getting your Luger up and running reliably. They are such a pleasure to shoot, and quite accurate if one does one's part.
