Shrub Identification

I'm having a hard time identifying a shrub on our property.  We moved here only a few months ago so I don't know exactly how this plant looks in all seasons.  However, here is what I do know.

It seems to be a woody shrub that grows 5-10 ft tall, the leaves are simple, opposite, and obovate (maybe?) the red to purple berries grow in 4's with a single, large (relatively) pit. The leaves are dark green and slightly waxy.

My best guess from google-foo is honeysuckle, but from what I've read, honeysuckly contains many seeds...

Dogwood, leaves aren't quite right shape.... hm.

Buffaloberries, fruit shape is right, clustering is wrong, leaves are wrong.

Think I found a match. Tartarian Honeysuckle.
