You're not the only one.
I found that out from someone esle at the same time I found out that you can charge the Magma Bazooka. I had beaten the game like twice before I knew that.
Makes me wonder what other properties weapons have. I'm just listing all the ones I knew/thought were obvious now:
- Jewel Satellite reflects projectiles back at their attack.
- Hornet Chaser retrieves all items save for E/M tanks.
- Laser Trident pierces shields
- Tornado Blow lets you jump higher when it's in use (good for speed runs)
