I need some suggestions here. I own a series 70 govt. model that has a stovepipe jam about once or twice every 50 rounds. I replaced the stock spring with a 18.5# Wolff spring, added a new wilson firing pin plate, and a wilson extractor which I believe is properly tuned. These improvements did nothing. I still have a stovepipe jam about once every 50 rounds. Anyone think I need to replace the ejector as well? Thanks in advance for help!

Have you had the ejection port opened up a bit? This is one of the most benificial alterations one can have done on a 70 series. Look closely at your fired brass. If the cases suffer from dented case mouths I would recommend you have the ejection port opened up like the new Colts, Kimbers, Baers, etc. It improved reliability in my 70 Series.

It would also depend on the ammo you are using. I shoot very light loads in my GC's; about 8,000 lup. With these loads, I use a 10 lb. recoil spring.
I assume you are using full power ball ammo; if this is the case then you should not get stovepipes with the RS you are using.
One other thing; the extractor on the 1911 is not a drop in part. Ed Brown had an article on this in American Handgunner, and I was amazed at the amount of hand fitting it required. It is true that most replacement part ejectors will work if dropped in, but they might not be fitted perfectly, and jams would be a sign of this.
