Stainless Lugers Quality

My Aimco Luger is more accurate than it has quality. It looks nice and feels nice but looking at the internals, there's little pits or holes on different parts. (Example the breech block along the slide area). The safety will move or drop down when shooting and you have to push up on it to fire, maybe it's an auto lock feature.

All in all I think its a kick to shoot, especially when I use the right ammo, some ammo will dimple the primers and I have to retry 3-4 time before they fire. I am sure if I had a Gunsmith look at it they could improve it somewhat. Anyway thats my opinions. Thanks
