The Strike Industries Glock 43 barrel does the job just like other barrels, but this one is fluted to reduce barrel weight. On top of that, the added Strike Industries style design is great for anyone looking for something more exciting than just the plain OEM barrel.

True Precision Glock 43X. The quality is similar to the Faxon barrels, but it's slightly more expensive. I think the main difference here is based on preference and budget. Just pick one that you like, and you won't disappoint.

Zaffiri Precision - Best Ported Barrels

The Zaffiri Precision has similar offers as Faxon and True Precision, but they offer ported Glock 43 barrels with flush and crown cut that others don't. If you're building your Glock 43 to significantly reduce recoil, Zaffiri offers some great options if you already have a ported slide to go with it.
