AMMO POWER, EJECTION PATTERN AND THE MAINSPRING??

[Heinmot]

With my now dead-reliable 42 Luger, I am wondering a bit about the now-functional setup.

First, I had to replace the mainspring with a Wolff and as it turned out, a 36-lb {2 lb lighter than what I was told is normal} and I had to change mag springs, too.

I ONLY shoot standard loads {several hundred rounds now of S&B, and Win white box 115's but did shoot a box of experimental American Eagle 147 FMJ Flat Points}.

Ejection pattern is very high, and generally to the right-ish front-ish of the shooter, with an occaisional case ending up just to the left of the shooter. Both me and the kid are left-handed which can alter a bit normal ejection patterns from righties, I know.

Here's my question:

The gun likes the lighter mainspring for reliability. It is totally reliable now.

BUT, am I beating the gun up using a lighter than normal mainspring?

I figure a lot of Lugers, being old, have essentially, for all intents and purposes, lighter than normal springs due to set over the years, but I am just curious.

I will NOT be shooting +P ammo in the gun, and from what I have read, some seem to get best reliability WITH +P. I don't shoot +P in my other 9mm's, and that was one reason I wanted to have the Luger setup to handle normal ammo.

Anyway, any comments?
