These high-quality magazine springs eliminate feeding problems caused by weak and worn-out springs. This is especially true in semi-autos.

Tip: The indication of a weak magazine spring is when no shell has fed onto the carrier, but shells are still in the magazine. Normally this occurs when the magazine is about 1/2 empty. Springs should be replaced every 400-500 rounds or when the spring has shrunk over 3" from its original free length.

Approximate free lengths are:

7-shot----------32"
8-shot----------34"
9-shot----------37"
10-shot--------40"
