Does any one have a SR1911? I'm curious because I noticed on the breach face opposite the extractor on mine there is one little section of it that is raised several thousandths of an inch higher than the rest. I notice , when inspecting brass , that it is leaving an indentation on the back of the cartridge after fired. This is on factory cartridges. The space where it's raised is in a spot where it looks like it could be a defect. The has not given me any problems as far as feeding an accuracy. It's been great for both. I'm just wondering if this is just on mine or all of them.

JRWhit,
I have not noticed it on mine and I am tickled pink of it. Only problem is within me having it for two weeks my daughter came home from college went to the range with me and fell in love with it. After all these years of shooting with me she has only laid claim to one other pistol and thats in 22lr. The problem with that is for these to be truly hers we have a promise that I would never take them to the range without her
But she has to continue to make the Dean's List and she has so it has been a long time since I have had mine to the range since she is away in college.
But here are the original reviews I wrote of her SR1911

It's a machining defect, and it's one to be concerned about. The thrust generated by the equal force places a side load on the slide instead of straight back.
Send it back, and don't take NO for an answer.

I had a Wilson CQB with that very same defect, except the indentation it left in the brass made it unreloadable. I sent the gun back and they stoned it flush, however when I got the gun back it now had .011" clearance between the end of the barrel extension and the breechface. When I emailed them, was told not to worry about it.
This was Wilson. I wonder what Ruger's response will be.

Just pulled my daughters SR1911 out of the safe and carefully looked I do not have this raise. The breech face is fairly smooth and even.

Any kind of step or shoulder in that area, or being out of square, can't be good.
I had two Kimbers that were like that. To me it looked like they did not finish the machine work. I fixed them myself, but it's tricky, and I don't recommend it. I still have one of them. It runs great, and doesn't mark case heads.
Yep.
The pic is the Kimber Ultra II I fixed.

no that's assembled. sorry I was looking at the two fingers over the top of the barrel extension for the chamber view port. It makes contact but the rest of the barrel extension has a little gap.
Take the slide off. Reinstall the barrel and bushing, and put the assembly up against a light source or use a feeler gauge. You should have some clearance between the breechface and the barrel extension, or the two fingers as you refer to it. Pull the barrel away from the breechface while it is locked up in battery.

Why are we worrying with the barrel hood? The problem is the badly machined breechface.

I just inspected my SR1911, and everything seems to be in order. I’ve never noticed any marks on my cases…but then again, I wasn’t looking for anything. I’ve had nothing but good luck with my Ruger.
What problems could this defect create?

Here is what I'm calling the fingers. The top makes contact with the breach face while the rest maintain a gap. Think I'll leave the specifics to ruger. It's too new to try a home repair.

It places a side load on the slide when the case slams into the breechface, and puts all the tensile stress on one side of the slide. The eventuality is that the slide will crack in the port...probably adjacent to the breechface...which isn't a good thing.
If they simply machine the defect out and make it even, it may create a condition of excess headspace...or not...depending on whether the surface of the defect or the surface behind it is to spec. They'll make that determination when they get the gun back.

Headspace came up as 918v sent in a Wilson with a bad J Cut and received the pistol back with a noticeable gap between barrel hood and breechface. That won't of course provide proof of excessive headspace but does indicate that in that particular repair the entire breechface was resurfaced, assuming there was no gap before.
Exactly. There was no gap. Wilson removed .010" of metal, reused THR same barrel, and told me not to worry about it.
My SR 1911 had some clearance there. The OP's Ruger prolly has some clearance already. It would suck if Ruger resurfaced his breechface and doubled the headspace.
I suggest you mark your barrel somewhere they won't notice before sending the gun back.

Ah! Okay. So what we've got is that a repair was done on the cheap instead of actually making it right...assuming that it resulted in excessive headspace.
Interesting. Did you gauge the headspace?

No, well not with a headspace gauge. But a 45ACP case would sit well below flush with the barrel extension. So I had that amount of headspace plus whatever they added by resurfacing the breechface.
My Pro has almost no clearance. And maybe .010" of headspace. Thank Goodness 45ACP brass is so short.

o.k. wait. I'm stupid.I got out the feeler gauge and finally realized what you meant. Their is about .008in clearance at this point between the barrel hood and the breach face when in battery. I'll take note of that and recheck when it returns. Thanks 918v. I hadn't thought of that. Hopefully head space won't be changed drastically.
