Lloyd: if you have any spare 45 barrels hanging around try one of them in that Springfield and see if she functions any better. If it does then I'm sure it is the barrel and will continue to recommend you get an aftermarket accuracy barrel either installed or install it yourself. I mentioned in one of my previous posts on your first Grrrr post that I have had fabulous results with a Ed Brown drop-in accuracy barrel. Possibly that will work for you too. HTH. Mikey.
