I'm new on here. I inherited an old PPK (early 60s era) from my grandpa that I hadn't shot since I was a kid. I took it out the other day and shot a couple magazines at 10 yards I couldn't hold a group less than 5"?! As a comparison I shot a couple magazines of the same ammo through my LCP and they were about 1.5". The PPK is in perfect condition and I can't see any obvious issues after tearing it down. What are the first things I should take a look at?
