Would people still be able to create firearms, machines and rockets as compact as modern-day firearms in a high-oxygen environment?

So me and my buddy are currently working on a story that takes place on a different earth-like planet similar to when dinosaurs like Brachiosaurus inhabit the landscape. A few differences is that the 'Humans' that evolved on this planet are much stronger and faster thanks to the increased oxygen in the atmosphere. (33% of atmosphere to be specific)

The people on this planet so far have advanced in the renaissance era of technology. But instead of combustion-based firearms, they utilize airguns as the standard ranged weapon. Combustion weapons like cannons, blunderbusses and grenades are still in use. But guns as compact as the revolver would just make the gun explode and render it useless. I also remember things like electricity won't work since it would overheat due to oxygen, at least that's how I remember it. Though that might be a different question on itself though.

As for the question. Assume they had access to the same materials we did when we made our first renaissance firearms. Would they still be able to make them? and if so, can they be just as effective? and to go even further, could they even make them as compact as modern handguns and rockets? If This is true, what mechanical differences would we expect?

This question specifically asks if it's possible to develop the combustion weapons. The other question specifies something similar, but only the performance and possible differences.

How would modern firearms behave in a high oxygen atmosphere?
