Springfield G.I., an affordable 1911

[gregarat]

Im up to around 400rds. fired total. The gun is still giving me trouble feeding the last round into the battery.
Today I went to my smith again. He says that the recoil spring feels light, and replaced it with a 18.5Lb Wolff recoil spring. He fired a single round Twice, then shot a full mag without problems.
I kinda felt a bit uncomfortable, having a 18.5 Wolff recoil spring when the gun comes standard with a 16Lb spring. So I did some internet research. On 1911forum people say that Springfield Recoil springs with yellow paint on the end is in the 14Lb range. Guess what my Springfield recoil spring has on the end... Im first going to call customer support, and try to speak with a smith instead a normal phone operator, and find out what the truth is. If I cant get anywhere with them Im going back to the smith to try to exchange the 18.5Lb spring with a 16Lb Wolff one. f that doesn't solve anything Im going to send the thing back to Springfield. This is really ticking me off!

Does any other Springfield G.I. owners have yellow paint on the end of their recoil spring?
