Slugger makes another single piece aluminum bat known as the 519 Omaha. This bat, however, does not have the extended composite end cap like the 619 Solo or Velo Hybrid. As such, expect a heavier swing weight. Barrel sizes are about the same.
It runs a few dollars cheaper so if you're looking to save a few bucks then the 519 is a reasonable choice. Or, if you need something that swings a bit heavier than the 619 Solo and want to save a couple bucks then the 518 Omaha it is.
What is the quick review?
We took the 2019 Slugger 619 bat in a few different sizes to the fields and cage.
What models and sizes are available?
After hitting and then reading everything we could on the bat, as well as discussing it with a few major vendors, we write this 2019 Louisville Slugger 619 Review. In short, the bat is recommendable across the board. Compared to last year it no longer has the Lizard Skin grip. But, that is far from reason to still not love this bat.
How is it built?
As we mention above, the 619 Solo is a single piece bat with an extened compostie end cap. This allows it to be one of the lightest swinging BBCOR bats on the market. The USA and USSSA bats have a similar balance point.
By our measurements, the 619 Solo sits as the same swing weight as the lightest bat on the market which is the 2019 DeMarini CF Zen.
As you change lengths you'll find that the rankings of heaviest to lightest BBCOR bats stays very similar. In other words, if you are looking for a 30 inch BBCOR bat the below rankings hold true.
How does it compare?
There are virtually no differences between the 2018 Slugger 618 Solo and the 2019 Slugger 619 Solo. Both are single piece bats with some tech in the handle to reduce vibration. They also use an extended composite end cap to bring down the swing weight. As far as we can tell there are also no difference in size offerings compared between the two.
In other words, we'd recommend getting a deal on the 2018 SOLO if you can still find it new. Most bat's inventory lasts through the holidays. But, come spring of 2019 expect the 2018 Solo to be in short supply---especially in popular sizes.
