So you’re pissed at Sig Sauer for not sighting in your firearm? That seems like a pretty lame reason to be upset with a company. Sight in your own firearm. It's not rocket surgery.
Sig put the wrong front sight on my p320. It shot crazy low.
Only after they sent me a new one that was the correct height did it shoot decently.
Rear sight was also visibly off center.
Not a big deal but it shouldn’t be that way. HK does in fact sight in their pistols from the factory. At least visually center the damn things.
I have a love hate relationship with Sig. Their customer service blows.
