Is the Glock painted? It sounds like it is.
I owned a G27 and carried it every day for more than two years. It had no scratches on it when I sold it. I have an M&P 45 that gets used plenty and it has no scratches on it.
You keep bringing up this issue of scratches. I hate to tell you, but that's the life of a carry gun or even one that gets used a lot. I have over 15,000 rounds through this shotgun:
I can guarantee you that I'm way more particular about it than you are with your Glock. Even so, there are a couple of marks on the stock. You'll have to look very close to find them, but they're there.
The point is, stuff that gets used will look used over time. If it's really bothering you, you only have three options:
- Complain to Glock and see if they'll replace the frame. (unlikely)
- Stop using the gun and keep it in the safe.
- Sell the gun.
Otherwise you'll have to deal with the marks.
