Please, put away the Dremel, put away the Mother's, put away the file. If it's going that far forward, it has nothing to do with the feed ramp.
Send it to Springfield and make them fix it.
I had two EMPs--the second was a factory replacement for the first. I have told my story before--if you care to read it, do a search on my user id and "EMP".
Bottom line--both mine were troublesome little buggers. But Springfield worked hard to make it right, and mostly succeeded.
I bought mine when they first came out (early 2007, s/n 1073). Most of what I have read since then has been very positive, so I believe that Springfield has the EMP figured out by now. Their Customer Service is very good. You paid top dollar for the EMP; make Springfield earn their money.
