I ordered an aluminum guide rod for my P-01 and haven't noticed any wear through 500 rounds except for a very small chip in the head of the guide rod but it could have shipped that way and I just didn't notice, again VERY small chip.
One thing to mention is that the aluminum guide rod is slightly thicker than the polymer guide rod so the stock flat coil spring scrubs against the aluminum guide rod. I ordered a round coil 17lb Wolf Spring to stop the scrubbing and have had no issues.
