My wife and I are running that load in our Gen-4 34's with the factory RSA. No cycling issues at all. The recipe came from a friend that has been shooting it in Production class for years. We have been practicing with it and shot our first match with it last week. No issues. It runs very well and a very soft recoil. It has no problem taking the big poppers. My OAL is 1.15 which is about the max that a Glock can feed.
