With regard to your trigger reset problem, the disconnector is the small pin at the front of the sear bar. This pin has an internal spring and that area can get dirty and lubrication inside it can become viscous and either make it stick or slow down.

Please note that the fitting of the trigger linkage on a Luger requires some experience and skill, and you should resist making any changes to "fix" the problem. Look to cleaning and proper lubrication first to solve action problems.

It's true that the Luger has a finely balanced action. This means that they can be ammunition sensitive. I've found that modern standard velocity, 115 or 124 grain full metal jacket ammunition runs best in my Lugers shooter pistol.

There is a lot to learn about Luger pistols and many fine details to understand about their markings. I'd suggest some careful study, including the free FAQ document we distribute on this site, before proceeding to purchase more.
