I just took my new PM45 to the range for quals and initial break in. Ammo used was Speer Lawman 230gr TMJ and Speer 230gr Gold Dot. Several things occured and I inclued some photos.
Zero rounds fired showing the dent in the upper portion of the guide spring tunnel.

Same after 120 rounds.

The majority of empties struck my helmet above my right eye in the forehead area. I have nicks in my helmet and a black mark on my face to prove it. After 100 rounds of ball I thought switching to the gold dots might have an effect. I still got hit and two same malfunctions occured.

The malfunctions occured on the last round fired and cannot be cleared quickly. Notice that the casing was pulled into the mag feedlips and wedged into mag and ejection port area. The mag cannot be removed until the casing is pried out. The feed lips of this mag are now bulged about 6 thousandths. Below will be a couple of more pics.
