I just got a brand new Glock 21.  I put 100 rounds of wolf ammo through it and approximately 85 of those rounds hit my face, head, or body.  A few rounds went to the right as they should, but a few also went to the left.  Does anyone know what the problem may be.  I am thinking one of two things:

1.  New Gun, weak ammo....needs to be broken in and use some higher pressure ammo to push the slide back fast enough to correctly eject it.

2.  Bad ejector or extractor or both.

If anyone has any ideas, please let me know.

PS - I am going to clean it up real good and try again with better ammo.  During this run it still had the gold lubricant crap glock puts in them.

#1 sign of weak ammo.

I have shot Wolf 45acp though and I didn't think it was weak at all.
