There's also 3281 gun murders in there (for 2019) where the type of gun was unspecified. Plus 840 murders where the basic type of weapon wasn't specified. So the real numbers are likely around 30-40% higher than the ones you're giving.
Just goes to show you, though, how the gun control crowd is concentrating completely on the wrong things. Almost 20X as more killings with handguns than rifles. We don't know exactly how many of those rifles are ones they'd call "assault rifles", but assault rifle murders are probably going to be something like 2-3% of all firearm murders. Plus, the number of victims who were killed in "mass shootings" is like 1-2% of all the firearm murder victims. But mass shootings and assault rifles are all those guys can talk about. If both of them went away overnight, gun violence numbers would barely register a change.
And that only goes to show that guns in general obviously need to be regulated better here. I couldn't care less about which guns make up which statistics. It doesn't change the fact that our stats are downright embarrassing when compared to other first-world countries.
