Laserbait said:Springs do wear out from compression/decompression cycles. Back "in the day", I suspect, manufactures didn't care if the guns wore out from the frame being battered (although some designs/materials hold up better than others). There was no internet for people complain en masse , so reputations were much safer.
That said, I replace springs when my auto's start acting funky, not before.
Agreed .... If it works fine, leave it alone.
