One is a HE the other 3 1/4" is a Regulation police. Got the 4 1/4" on off back-page for a steal the other off GB. Both are great shape outside, little pitting in the barrels but both don't seem to mind! I stuck some aftermarket "J" Frame grips on them cause the grips they came with are so dinky! The HE is #2814XX and the RP is #3810XX. Cheap to shoot! Accurate out to over 100 meters on steel! View over the sights on the HE at the Steel torso target at about 108 meters! Easy to hit!
