M9A3 Barrel for M9A4 (Full size)

I am currently rocking a Jarvis custom barrel in my M9A4 (full size) due to my factory M9A4 barrel having poor quality chrome lining. Today I stumbled upon a seller on GB with a couple of factory M9A3 replacement barrels for 190 USD a piece. I decided to give this a go to have high quality spare barrel on hand that is cold hammer forged and chrome lined. The part number on the barrel is JBM9A3TH and it does come new in box. Can anyone confirm if they have had good/bad experiences with spare M9A3 barrels, will this be a good barrel to keep as a backup? Should this barrel even replace my Jarvis custom barrel?
