Weak ejection

NWdude83 · April 25, 2008, 11:53 AM

I am looking at picking up a Steyr M9-A1 soon. But I heard they suffer from weak ejection. What can I do to fix this?

Welcome to the forum.

Work the bolt faster. My Steyr JCS has the same problem. If you open the bolt slowly, the fired case falls down inside. Going fast, as Cooper wanted us to do, solves the problem by getting the case clear of the wider portion of the action faster than the ejector can finish rotating it to the limit of ejector travel. When you extract slowly, the case mouth stops against the wider part of the action with the ejector having too little remaining travel to flip the case out of the ejector port. By extracting fast, it is still flipping outward when the extractor pulls it out far enough to see air.

The ejectors on those actions need just another half millimeter or so of extension.

Try again. The M9A1 is a semi-auto pistol, not a rifle.

In the medical field, they have a pill that can fix that problem!!

I have an M9A1 that I wouldn't take any amount of money for. It's a GREAT gun! However, you're right, it DOES eject weakly. Funny, but my S9 has a stronger ejection. Shorter=weaker slide spring? I don't know. You could always just shoot and duck. LOL! FYI, mine doesn't like aluminum-case ammo, either.

Check www.steyrclub.com, they might have something on this.

Good luck, and let me know if you find out anything.

Many European pistols eject weakly with American ammo. US-made 9mm ammo is generally loaded to lower power than comparable European ammo. You can either shoot European ammo, shoot the hottest US-made ammo you can find, or handload and tune your loads until the gun functions properly.

Huh. Curious I didn't register the model number. Running blind some days.

The other fellows are right about the ammo. U.S. liability attorneys have got the ammo makers here running very conservative pressure numbers. See if you can find some military ball and try that?
