Maybe it's OCD, but is this protruding too much? I'm thinking maybe it's sticking out a bit more than it was the last time I shot it. This is a P245.

I looked for replacements, and it looks like the old-school inner/outer pins are discontinued. Scheisse.

It's definitely your OCD. I've worked a lot of P220s and P245s over the years. If it bugs you too much, you can gently tap it back in with a taper punch so that it helps to flare the end of it. If you replace them, get an armorer to do it, or watch a video on it. Make sure the gap on the outter pin faces the 12 o'clock position, and the inner pin faces the 6 o'clock position as they are in the photos you posted.

I'd add, if you don't already have one, buy a proper roll pin punch, in the proper size. The roll pin punch has a dimple that rests inside the hollow of the pin, and does less damage to the pin, and is less likely to slip off in use.

That's honestly what I wanted to hear. Thanks. I've read some threads on Sigtalk about a loose pin allowing the breech block to move and fatigue the metal in the slide. So, it raised an eyebrow. May tap it back in, as you said. Will probably order some roll pins (now that I have the source) just in case.

Thanks again.

I’d tap it back in with a proper roll pin punch (pretty sure it’s 1/8th but my manuals are still in storage after the move) because you need to see if they move again. If it does, it’s likely that the pins are broken in the middle. This is actually pretty common with classic SIGs that are dry fired a lot without snap caps.

Replacing the pins isn’t hard, but there are pitfalls if you don’t know what to do. Bruce Gray makes an excellent armorer video that everyone with a classic SIG should own, IMO.

Those roll pins are a wear item and SIG recommended they be changed every 5,000 rounds at the last armorer course I attended (many years ago and long expired).

Yeah, that's what I was concerned about. Thanks for the tip on the Bruce Gray video--I will pick that up along with some extra roll pins. I don't dry fire it a ton... but I have.
