I have had my glock for about 3-4 years now and never had issues with brass to the face. Over the weekend though I had 2 ejections hit me in the face in a period of 100 rounds. The current ejector is stamped "336" and I have seen posts with other people having issues with this ejector. What do...
The magazines are cheaper for the XDs. That was my deciding factor in buying the XDs. The only problem Im having though is finding the standard mags in stock currently. Also, it depends if you like a frame mounted safety or not.
