Custom weapons don't have firing sprites.

The Flash state, that will let the shooting weapon flash overlay sprites to be shown, is entered when the Fire state gets called, so that should just work.

Since I see that you just added and AltFire state to your weapon, I believe that you're missing the flash when you're using the secondary fire and to fix that you just need to add a AltFlash state (You can just copy and paste the Flash state or even jump from the AltFlash to the normal Flash immeditaly).

Turns out I had to include A_GunFlash, idk why default weapons don't have it but still have flash.

Here's why

Default weapon's functions always call for A_GunFlash

This code does use that sprite (PISFA0), it's in Flash.

Flash:
		PISF A 7 Bright A_Light1;
		Goto LightDone;
		PISF A 7 Bright A_Light1;
		Goto LightDone;

Also, if you are looking to make small changes to the weapons you should be using inheritance. The ZDoom wiki warns of just copying and pasting the existing weapon code.
