How so?

Actually now that I think about it the Magnum usually have a slight transformation.

Interesting.

Trigger Magnum, with the exception of a couple of them, they all have to end in magnum. It's like how riders will do weird poses and say Henshin!. Worse with Accel.

It never noticed it until I saw it in Ex-Aid. Then Gosei mentioned the Bashaa Magnum, and then I saw Skull Magnum. And it just sunk in.

Yeah as long as it doesn't transform into another weapon. Figured that was a normal Kamen Rider trope.

Also, have you noticed that in Kamen Rider when a gun is introduced as a Rider's weapon it almost always has the title of Magnum?

Lol!

Another was a like a slightly demonic steam punk style gun that would inject a transformation serum. Not the greatest ideas when I came up with them in a couple minutes.

Alrighty then.
