I recently picked up my brand new PPQ M1 in 9mm, took her home field striped and cleaned the factory gunk out of her and also fully disassembled the slide to clean out the firing pin channel. The trigger had some grit in it in the take up but that has worked its way out a little now but i have only ran 100 rounds down her pipe so far. My ? is has anyone else experienced chafing inside the frame where the recoil guide rod sits inside that little channel? Also i noticed the underside of the barrel by the chamber has a nice linear scratch where the recoil guide rod rubs against the barrel?? Was wondering if this is normal for A BRAND NEW PPQ and it is just still being "broken in" or if there is something wrong with my new PPQ. I love this little firearm and would like to hope its going to be ok cause this is my new favorite gun BY FAR. I have a XDm which was my fav for awhile until i got my hands on this BEAUTIFUL PPQ. I might also mention this is my first Walther product I am very impressed just a little worried that my new PPQ had a problem already. The 100 rounds i ran threw her the day i got her had 0 malfunctions and ran great so great and felt so good in the hand i will be getting another PPQ in .40 S&W to replace my .40 XDm. Could anyone shed any light on this please cause i would love to keep this gun FOREVER but i fear even if i properly maintain it, it could have a problem is this isnt suppose to be happening to a brand new PPQ. I served 6 years in the Coast Guard on a Boarding Team doing drug interdiction off the port of Miami so my weapon maintenance skills are up to par with where they should be to make a firearm last for life so its not me im affraid. The chafing does wipe right out with a little scrubbing and cleaner but i dunno if this is normal or not. Thank you all for your help in advance, and any suggestions are welcomed by all means.
