I’m a little po’d. I realize it’s a gun and you will get wear but after dropping a good buck on a Trijicon RMR type2 you would expect the quality of the glock to be better. It wasn’t until I mounted the rmr that I realized how much wear was on it. If it turns out Irun shipped me a used barrel on my new gen 5 MOS, can’t say I will do much more business with them. This is my 7th order from them but 3rd gun. The other 2 were brand new with no marks, and my other purchases were great except for a couple of mags were pinned kinda sloppy.
