Question about ejection on my 92fs

I just purchased a NIB Beretta M-9 Limited Edition. I fired it with 50 rounds of German "Geco" brand 124 9mm FMJ. I never heard of this brand, but it looked great and functioned beautifully. It was accurate, reliable and ejection was positve. It accutally felt like NATO ball. I then switched to Fed American Eagle 115 gr FMJ. Although this round was reliable, the pistol seemed to not eject the cases very far. It only flung the casings about 1ft out of the pistol. I didnt have any more 124 gr to try out, but I assume my pistol likes hotter ammo. Could this be the case, or is there a problem with the pistol? Thanks for any input.
 
"Positive ejection" is dependent....

... of course..

What seems to get cases out of a self loader and into the air is "slide speed". Which is another way of saying "the quicker the slide moves, the more positive the ejection."
From what I've gathered, slide speed is more effected by bullet weight than muzzle velocity. Obviously, with similar weight bullets, higher velocity will move the slide faster.

Lighter loads will eject properly if the pistol is gripped firmly enough. Heavy loads have more margin of error for "weak wristing".

Varying the recoil spring stiffness will also change this function.

Those are the three major factors: Cartridge intensity (for lack of a better term), recoil spring tension, and firmness of grip.

Having said all that, if the cases get out of the gun, it works. One might allow for some dirtyness from use. Getting gunk (even burned powder) in the slide rails can slow up the works.

At any rate, I wouldn't be concerned about your sidearm. (Other than to make sure it's clean and lubed.) You might try a couple other brands to check it out. I'm pretty sure the Geco stuff (yes, I've heard of it, used some) is hotter than most U. S. manufactured stuff.
 
JRiggs, I have had this problem only when reloading some "very light" 9mm loads. In fact some were too light that they did not even cycle the slide.
