I was wondering if anyone else experienced some free movement with the extractor sitting in the bolt head??
Mine sort of wiggles just slightly but I was wondering If that my be a source of my problems with ejection?

I'm no HK9x armorer but I say tight. I like mine that way and my SW5 would never run with a bad spring/loose extractor. Others will chime in.

Nice and tight in my opinion, but also make sure the parts are in spec if they are after market.

I have seen tons of failures due to a out of spec bolt head and/or extractor.

Thats why it pays off in a million different ways to go all HK German with internal parts.
