Gun jamming with new barrel - Lone Wolf Arms AlphaWolf Glock 27/33 9mm Conversion Barrel

Upon my first qualification with the new barrel in November 2022 I had no problems. I fired about 200 rounds through it with no problems. Upon my qualification today I had multiple misfeeds and jams. I tried several different magazines and our range officer shot it as well with the same malfunctions. It is disappointing as I was hoping not to have to purchase an entirely new weapon but just change calibers from 40 to 9 so that my magazines are interchangeable. If anyone has a fix I would love to hear it, otherwise I will have to purchase another backup weapon. I must have a reliable backup weapon and not worry about it not functioning properly.
