SA 1911 issue

Send it back to Springfield. There warranty is the best in the business.

Second it. Send it to springfield...................warranty is awesome

I'm not seeing a problem here. Rattle is normal with the gun in battery, even a tight gun can rattle a bit with the rounds in the mag. If you're talking about rattle with the slide impacting the frame at full recoil, I don't understand how you can feel/hear a rattle at that moment. Are you able to replicate it somewhat by hand cycling the slide? Purely a guess, perhaps the recoil spring is kinking and causing some rattle? If so, it's not really an issue.

OK...Here's an update on the 'shake'.

Went to the range this morning and once again (shooting Federal 124gr) there was a very slight shake at full recoil. I asked the range officer to shoot off a mag and he also felt the shake. His opinion is its normal and nothing to be concerned with. As long as I have no failures or other issues, all is good. He has shot numerous 1911s in 45ACP - some shake and some don't. He felt if anything, recoil was less then expected for a 1911 in 9mm.

After talking for a few more minutes, he went back to the pro shop and brought out a Kimber 1911 in 9mm. Using the same mag, we both shot the Kimber. We both felt the Kimber shake (enough to be noticeable) but slightly less then my Springfield. The Kimber's recoil was more noticeable (makes me wonder if a heavier spring would minimize the shake further..in exchange for stronger recoil).

Bottom line is maybe I'm fortunate that my other 1911s don't rattle or shake. Its a slight annoyance that the Springfield shakes. Just something I notice. Each round still hits the target if my aim is true.

These suggestions might alleviate the rattle:

• Installing a recoil buffer like a Wilson Shok-Buff
• Lubricating the slide and barrel with Slide Glide http://www.brianenos.com/pages/slide-glide.html

Some info on Slide Glide:

Advantages over other oils and greases:

I recommend either Slide Glide Lite or Standard. The Heavy formula may be too thick/viscous for a 9mm 1911 in cold weather.

I just read your posts from the top today.
This "shake" is hard to quantify.
My assumption is that it is being caused when the slide is at it's furthest back.
Check the contact between the guide rod and frame to see if it is excessive. If it is then the recoil spring is underpowered. Using a shok buff would also ID this issue. You could try different weight springs.

I tried using a recoil buffer a few weeks ago as I thought it would preserve wear-n-tear on the gun. But the same shake occurs with or without the buffer. Haven't bothered putting it back on. In princible I have no issues using a recoil buffer but if it was meant to be used, SA would have had it installed from the factory (I think Wilson has them installed from the factory, but I could be mistaken).

Interesting.
I agree that shok buff should not be needed, I hate adding wear parts in a firearm.
You tried running just the slide on the frame. Is it loose when the slide is to the rear?

I was hoping someone had an idea whats going on. For the first 200+ rounds thru this gun, I didn't get this shaking. Other then this shake, the pistol is great. I'm thinking of sending it to Springfield but would rather understand whats happening and if its something minor that I can remedy.

Maybe the gun is " loosening " up after the the first 200 + rounds. Sort of getting " broken in ".
