I purchased a Sig Scorpion 1911 yesterday, took it to the range last night and ran 150 rounds of Remington 230 gr ammo through it and 1 box of Hornady HP ammo. The gun ran flawlessly for the first 100 rounds then started to occasionally FTF. It would feed the round but would stop maybe an 1/8 of an inch from completely closing. I was able to push the slide the rest of the way closed and fire the round. The next round might feed perfectly or it might not close fully into battery. The Horandy HP were run last and more than half of them fed and fired great but the rest had the same issue. There were no issues at all with extraction. Since it ran so well for the first 100 rounds, was it just dirty or do I need to have some work done on it? I cleaned it before going to the range and after getting it home and it was dirty as hell. Is Remington ammo (green/white box) that dirty? This is my first 1911 in a very long time and I want it to be my EDC replacing my Glock 21. Any thoughts? And should I have any work done to it? Thanks for any feedback.
