Do we forget that cops were primarily still using 6 Shot Revolvers well through the mid 80's? It wasn't until after 1986 that most departments then relented and went to autos. Capacity wasn't really an issue then... and honestly really it's not even an issue now.
Those are flat out good looking guns.
Oh. I looked at the last picture and didn't see it. Looking at the 4th picture now that you mention it, I can just barely see it. And now knowing where it is, I can sorta see it in the last picture. It's a little fuzzy.
