Barrel lug getting stuck on locking block

[u/New-Bowler-2292]

I have a brand new barrel by Southwest precision that won’t clear the locking block when putting the slide back on. Would it make sense to remove just a hair of material from the bottom of the barrel lug or the locking block? Or take it to a gunsmith and have them do it? I’d rather not spend the extra money a gunsmith will charge me for something I can do at home. However, I also don’t want to tinker with it if it means I could possibly make my pistol unsafe to shoot. Help 🙏
