The .380 Aguila is a weak load. Not saying that's it, but there's a good chance it's an ammo problem and not a G42 problem. Try running some Perfecta [or other sufficiently powered loads] thru it and see how it does. Since Glock made a few updates to the G42 it's every bit reliable as any other Glock, but it still requires sufficiently powered loads. Glock has one the best customer service departments and fastest turn-around times in the industry. Call Glock and ask for Dan Kuczynski. He will 100% make sure you are taken care of.
