We finally had a nice weekend here in MN, temp was 29F but with the sun shining it felt a lot warmer, so I bundled up and headed to the club.  I took 200 rounds of 185gr over 13.0 gr of AA #9 which provides 1215 fps on my chrono in warmer weather through my Glock 20 SF.

I ran 40 rounds through my Gen3 Glock 20 SF, just because and then loaded up my new Kimber.  I ran 160 rounds through it and I'm very happy with the first outing.  Before I shot it, I put a Dawson fiber optic front sight and what I think are a beautiful set of Cocobolo hardwood grips from Fusion.  I still like the look of the Kimber with the black grips, but these are just too nice not to like.  I must have done a better job than I though centering the new front sight since my first 8 rounds at 15 yards freehand were spot on.  The target is a NRA D1 "tombstone" and I put a small piece of painters tape in the center to give a smaller aim point.

All 160 rounds went through flawless and this gun is way more accurate than I am, very impressed by what it can do when I take my time and really aim and follow through.  Any shot not right next the the last is my fault.  Next time out I will likely try a few shots from the bench and see what this Kimber can do at 25 yards.  Most of today was between 15-20 yards with about 20 or so at 25 yards. 

Only 2 notable events.  After about 30 rounds the base plate of the factory Kimber mag fell off.  The welds look like the just broke, I'm not very impressed by that.  The MetalForm mags I have worked just fine.  The other "event" was on the last round of one of the mags, somehow the brass must have bounced around inside the port and the slide slammed into it completely smashing the case mouth, the really odd thing is that it still ejected and the slide locked open.  With some of the negative stories I've heard of having to "break in" a 1911 I was very pleased that it didn't have any issues. 

I'm really liking this gun.

Did your brass look something like this?



If so, that is generally a sign of the extractor not properly holding the brass until the ejector hits it.  The result is the brass slips down in the action.  When the ejector does hit, it is not launched clear, but spun part way in the action.  Then as the slide comes back forward it munches the front of the case, and knocks it free.

That is EXACTLY what it looked like.  Is that something you had to address or is it just once in a great while?  Of the 160 rounds I shot it only happened the one time, though that's not a whole lot of ammo.

Thanks

When I first converted my Para to 10mm it happened to about 6% of the brass.  That meant 1 per magazine.  I finally figured out it was the last round of the magazine that it happened too.  And that it happened cause there wasn't another round coming UP out of the magazine to push on the empty and keep it in place.

I pulled out the extractor, increased the tension and re-installed.  Since then, every thing is fine.

since you have had just one so far, I would probably not worry about it.  If they get more frequent, put some more tension on the extractor.

sqlbullet, for the first time I just detail stripped the firing pin and the extractor, this is my first 1911 and I guess I expected a spring providing extractor tension, so was surprised to see it's just a solid piece of metal that tensions against the channel in the slide.  When you said to add tension to the extractor how would you do that?  Bend the extractor shaft itself?

Thanks

Here is a great write up with video on the wilson combat blog:

http://blog.wilsoncombat.com/uncategorized/checking-the-extractor-tension-on-your-1911/

They have some diagrams at the bottom and go over adjusting tension.  End result is yes, apply a little pressure to increase the bow.

Thanks for the link to the article.  I checked the tension the way the video showed and it didn't seem all that loose, but increased tension anyway.  I went a little too far the first time and it was too tight, it wouldn't feed very well (just dropping the slide and racking by hand).  I tweaked the extractor a little back and feeding seems reliable again, so I'll see if it makes any difference the next time out at the range.

I traded for a new Kimber Target II- 10MM this past Saturday and took it to the range Sunday afternoon.
Shot my Nosler 135gr HP at 1450 and 150gr at 1350 reloads with ease ,loaded at 1.245". I also had some cast 200 gr LFNPB at 1100, OAL = 1.245". all ran fine in the Kimber. I will try to get a few pics taken.

That's awesome.  A brand new 1911 and it's feeding like a champ.  Kudos to Kimber.  Especially awesome being that they have such great case web support at the 6 o'clock position which wouldn't generally enhance feed reliability over other more opened up chamber mouth designs.
