Thanks in advance.
mike benedict said:You probably won't see an malfunctions until the spring is totally shot but you are risking frame damage.
Glock did not recommend changing springs until they started to see frame damage and broken rails on the .40 cal. pistols.
Now they give you a sack of springs and tell you to replace them often.
Springs are cheap insurance
