Can you guys give me the lowdown on these?
I believe the different models were the C3, the RCS, and there was also a GSR.

Reliable?
Any quirks?
Interchangeabilty with other CCO parts?
Used prices?

Thanks

I've had a C3 for 3? years now and it's been nothing but reliable.  Its been my primary carry piece since l bought it.

My main shooting friend liked it so much he replaced his worn out carry piece with one.

He's had to send it back to Sig three times and it still isn't as reliable as mine has been.  This last time Sig even mounted their night sights for free for his troubles.  iirc, it's been feeding issues.  It's been a while since (last summer) we've discussed it.

As much as l love mine based on this (limited sample of two) I'm really hesitant to recommend the Sig C3 to anyone.

But the CCO size and style is the perfect size for a 1911 carry piece.  Sadly just maybe not the C3.

A buddy of mine has a Commander size Sig and it's been nothing but trouble.   Won't make it through 100 rounds of ball without a FTFeed.

Thanks guys. I think I will look elsewhere for a cco.
