Failure to feed, did I diagnose…

Correctly? Ruger SR1911 commander with FTF issues. It doesn’t like to feed at all. You can not “slap” it into battery. I’d call it a 3 point jam but I’ve not had an expert confirm that.

What I’ve tried

- Different recoil spring weights (slim, but ya gotta try)

- Various mags…Ruger, Springfield, Wilson, nighthawk

- double, triple checked “plunk” for rounds

- run same load & mags in my Kimber (5”)

Using 200gn w/ 5gn titegroup = 845fps in 5”

I’m down to extractor?? Seems a long shot but it’s either that or the throat angle (how would Ruger mess that up)

I got it 2nd hand so no real history.
