Simple jinx should cause most firearms to fail or jam
In a universe where guns exist and level-1 wizards can cast magic missile/fireball and cantrips like firebolt, setting fire to things (like gunpowder), my bet is that low-level magic users aren't going to be trumped by steampunk-grade tech that easily
You could make that argument for almost any weapon though. The physical meddling required to snap a bowstring, dull a blade, or even just put a rock in their shoe is minimal. Magic needs to have limits if you want the mundane to compete at any level, and one of those limits is often an unspoken acceptance that you can't just arbitrarily foul another person's gear.
