Hi, We fianlly bought a new in the box Steyr M-9 this weekend. I cleaned/lubed it per the manual and took it to the range with 300 rds of Remington 115 grain UMC ball. After maybe the 4th magazine the slide refuse to go into battery all of the way with a live round and was jammed in that position until I got it unjammed. My Walther P-99 and USP 9 gobble up UMC all day long with no problem. I love the ergonomics of the weapon and hate to have it serviced so soon. Any wisom or help is greatly appreciated!
