Well, I have very little experience with Winchester's customer service, but I can tell you for sure that as of about a year ago, Winchester would still send you a new firing pin if you called in your serial number. I had a Win Model 100 that sat in my closet for about 20 years. I never did the recall repairs until I decided that it was time to trade it off. I just couldn't trade it away without making sure that a known issue had been fixed.

If you ever have a real need for more than a couple of magazines, your problem is not a shortage of magazines. It's a shortage of people on your side of the argument. -- Art Eatman
