I have been reading on here about some people were having some issues with there Springfield 1911’s getting hung up as the slide closes and catches on the disconnector. So I got out my RO Operator in 9mm and if I manually close the slide slow, as soon as it comes in contact with the disconnector it hangs up there, also I noticed the slide closes slower then expected during recoil. So, I emailed Springfield and asked what weight recoil spring this gun uses, and the reply was a 9#.
So I got my Kimber Custom II duel tone pistol out also in 9mm and tried it. It worked fine, the Kimber uses a 12# spring, so I thought I would try something, I ordered 12# recoil spring from Midway USA, replaced the spring in my RO, and bingo, issue is gone, my RO works good no, now more issues. This may help others who have been having this issue, I just don’t think the factory 9# spring has enough force. I just did this out of curiosity.
