Panthera weapon primary fire is stopped by Gara's 4th ability from the inside.

With all other weapons I've tried, you can shoot through the wall made by Gara's 4th ability from the inside just fine. However with the Panthera, the sawblades you're shooting out bounces off the shields on the inside, and never gets to any targets. 
 

I haven't checked with the Miter weapon, but I'm assuming it'll be the same as it's also shooting those sawblade discs, but I can't confirm.

I'm not sure if that's a bug, the sawblades are meant to bounce off any surface.

Surely it can't be right that from the inside they bounce. That makes the weapon completely useless playing Gara (or playing in a squad with Gara. It would make sense if they bounced on the outside, just as you can't shoot through Frost's 3rd ability from the outside. The weapon functions fine from the inside of a Frost bubble.
