Ruger says it is ok to shoot steel case ammo ( Wolf) in its 1911s. However, when i tried to do this I was getting a lot of failures to feed. Slide locks open and fails to feed the next round. I am thinking of trying a stronger recoil spring. Has anyone else had this problem?

Personally I won't run steel cases ammo in any of my autoloader. Wolf ammo is not very high quality in my opinion It sounds like your gun agrees with me. Try different ammo before you start changing things.

There is a specific "dance" between the mechanical parts and springs during the cycling. Steel ammo behaves differently than "brass". Changing springs may solve the problem with the steel cases but might create a problem with "brass".

Google: "slow motion video of the 1911 slide cycling"

You will see a slight dwell at the beginning and in full recoil. This is dependant on brass cases. Steel doesn't expand like brass!

I shoot Tula steel in my SR1911 with no issues.

Wolf ammo is fine in terms of quality and is mostly what I use in my 9mms. In fact, I think it is better quality than some brass out there. I've had short loads in BB.

The issues in 9mm 1911’s I have experienced with steel or aluminum cases was magazine related. Typically top round of a full magazine...certain mags only, not always brand specific. The feed lips cut into the cases during feeding, slowing the slide thus cutting momentum.

Disassemble the magazines. Debur inside lower corner along the length of the feed lips. Then polish them. While you are in there, polish the sides of the followers and debur the inside of the mag body at the witness holes.

I have a 9mm Ruger Commander and was told by 'one of the top 1911 builders' that the Ruger come with too light of recoil springs and that I should change to a 14# one. I have not had a chance to go shoot since I made this change though.

I changed my recoil spring to a 16lb, no issues. Didn't have issues with stock spring either, but it felt sooo weak, like it was just on the verge of a fail, so I changed it. Now it feels strong.

I have a new (one range trip) Ruger 1911 target model in 9mm. I also have a much used Ruger 5" in 45 acp. The 9mm model have a very strong recoil spring, equal, in my opinion to the .45. Maybe it's still tight but plenty of spring. In fact it ran poorly for the first 10 rounds.

I have shot -not much, but I have shot- Wolf, Tula and aluminum cased ammo in all all 3 of my Ruger SR 1911 with my typical 1% failure rate that I might get from brass.
