mainspring tension

What mainspring changes would be normally due to compensate for a 6" barrel having been installed on a formerly 4" P08 ? One misfeed nearly every clip, tried many clips, only one seems to work better, but the others are fine with rest of my other Lugers. I am thinking the longer barrel is slowing the stripping / chambering process down, maybe causing these misfeeds.

Hi:

The variables you have to examine are many with the Luger misfeed problem. Someone really familiar with Lugers would have to examine your individual pistol and check several variables first, among these:

1) Magazine condition, including proper magazine spring tension

2) Ammo you are using, including proper OAL, charge and even the powder type

3) Extracter operation and spring tension, as well as, feeding ramp condition

4) Recoil Spring condition and tension

5) General condition of pistol's moving parts, proper lub., etc.

That being said, and all other variables being within spec., you would probably need a weaker recoil spring, to compensate for the heavier barrel (and thus receiver unit).

My LP-08 (8 inch) needs stiffer ammo to function properly, much stiffer than my regular P-08 models.
