Savage, Stevens and Fox 311s are good values. Vault tough and reliable. Yes, they do need some work to make them stay open far enough to get shells in and out. I have one each in 20ga, 16ga and 12ga. I'd have one in 10ga if they ever made one. All my 311s did need work to allow them to open and stay open. Chamber polishing is a plus. Since they are no longer made, you'll have to look for a used one.
Best luck.
