Lately when shooting my 39a I have noticed that about half of the spent cases just fall out the side and the other half get ejected a decent distance. Sometimes the cases don't get ejected at all and I have to clear it manually. I am assuming that the spring is tired and needs to be replaced, but the fact that some cases eject ok has me a bit confused. What is the opinion of the group on this? I don't know if the spring has ever been replaced. Thanks.
