Reg Pin Size or Large on LEO Only/Restricted 6920's

I’ve seen a few 6920’s around the inet that have the old Law Enforcement/Military/Export Only markings. Were these made with small or large pins? I’m not sure when Colt went back to the standard size.

Thanks HKd

I know this one. The transition to standard size pins occurred in 2009. S/N LE060000 to LE069999 may have been built with either size.

Update: Just did a Google and some LE6920’s that have as low as S/N LE057xxx have the smaller pin size. 2009 does seem to be the transition year.
