I wish Black Hills was readily available and cheaper. I went to the range with 100 rounds of Federal Champion 115 grain fmj and 100 rounds of S&B 115 grain FMJ
I encountered 2 FTE with the Federal and one with the S&B.
The Federal spent shells were completly in the chamber and the S&B was about 1/2 out the chamber. Also there really was not a consistent pattern of ammo number. One was the last round in the mag and the other two where about in the middle of the round count in the magazine.
Two of the FTEs occured within the first 25 shots and the last near the 180 round mark so dirt or lack of lube I believe can be ruled out. (the gun was clean and lubed by Beretta USA)
It is interesting as I read about other Nano owners encountering problems they are always FTEs. I have never read of a FTF which tells me the magazine is doing its job.
Some Nano owners are suggesting the extractor is not working properly becasue the spent shells are not landing consistently in the same area and some shells are hitting the shooter in the head which I have encountered.
Beretta told me the Nano is a blow back gun and a consistent higher pressure shell like Black Hills is what it needs not a different designed extractor like some Beretta forum posts are suggesting.
I understand in general terms what an extractor does but my knowledge is very limiited and that is why I am asking my Kahr friends for some input.
Beretta told me my extractor is ok when they checked it out.
If shells are hitting the shooter in the head and spent shells are not droping in the same area is that an extractor issue or too little recoil? Also does the extractor pull the shell completly out of the chamber or does it just get it started and the recoil created from the pressure build up in the barrel do the rest?
Note: The two Federal FTEs all were completly in the chamber but the one S&B was half way out the chamber

Hey Russ, my Nano now fires Speer Gold Dot 115gr std pressure rounds just fine. My FTEs dropped from 7/100 to 4/100. I don't know if it's parts breaking-in or that I fixed the mag followers to drop freely in their tubes. I did that around 300 rounds and have 550 thru her now.
In my experience, how FAR a shell case flys (3 ft vs. 7 feet) has to do with the strength of the recoil spring. It's one way to know when it's time to replace one. I'll admit its hard to gauge in a shoting station as mine hit the partition. I have a Kimber Rimfire Target gun which ejects shells which hit me in the face. It turned out they were deflecting off the partition and the "problem" went away if I stood one more foot to the left.
I had an experience with a Sig 1911 RCS which failed to feed the 7th (last round) on both the factory Checkmate mags. Once I installed a new recoil spring, that problem disappeared immediately.
Sometimes problems are hard to diagnose because guns are systems of parts and springs which need to work as a team.
You've already read that the extractor only does the first part of the job of clearing a shell, the ejector does the rest. I agree.
I think if you are 100% when shooting SD loads, I'd carry and be patient about the range ammo, they'll get it fixed before long.
