Try this test

Would you guys do me a favor?

Try loading a full magazine in your Micro 9. Just a full magazine, not the mag +1. Then rack the slide to chamber the first round. Fire that round. Then hand eject the next one and inspect the bullet nose.

Then let me know what you find.

Yep. Exactly. It is weird because it only happens on the 2nd round. And it only happens when I fire the gun. I sent it back to Kimber and all they did was hand cycle the action. When they shot it at the range they never ejected the loaded round to ccheck the nose.

With my gun it doesn't jam, just dents the nose. All the subsequent rounds are fine. What happens is, when I slingshot the first round in the chamber, the second round gets pushed forward a bit. When I fire the first round the feed ramp shoots backward and down hitting the nose of the second round before the slide even comes back all the way.

I don't know how much magazine nose-diving plays a part.

Be careful though. The force that dents the bullet is enough to also push the bullet back in the case.

Does anyone know of a fix for this?

Interesting..... I've never had any issues with my Micro 9 but I will try to go to range this week and perform this test to see what the results are.

Whenever I slingshot the slide on my Micro 9 to load the chamber, I then remove the magazine and "reset" the top round in the magazine, as it will have always slid forward farther than it should from chambering the top round.

Simple fix, resolves the nose dent problem.

Sure it solves the problem if you don't want to carry 7+1. If I load it +1 style then it dents the third shot. Round 1 is in the chamber, round 2 has not been pushed forward, round 3 is the one that gets pushed forward when #2 was chambered. After that it seems that the bullet noses get scooped up by the ramp rather than smashed by the bottom edge.

I've never seen that either. Is it just with the micro series?

Have you guys tried ejecting that 2nd round before firing it? With my gun this was slipping past me because it didn't cause jams. So most of the time I just shot that damaged bullet without knowing it. It wasn't until the snow melted and I found several bullets that I began investigating.

OK. Thanks. As I described above, I didn't notice the phenomena until I found bullets after the snow melted - so it makes me wonder if it was "just my gun" or if it was common to Micro 9s.

Here is my concern:

The cartridge on the right has the dimple, but if you examine it closely, the bullet has also been seated deeper. Measuring with the micrometer it was 0.030" shorter. Since this happens upon firing JUST ONCE, I wonder how safe it is. I'm not an expert on semi-autos and I've been told the bullet setback is normal. But I always understood that to be in terms of daily loading and unloading of the same ammo, not just load-brand-new-ammo-and-shoot.
