Ha! I just made a thread about my own 1300. Mine isn't a Defender, it's set up as a traditional hunting gun though.

The thread I started asks how I can make it a more practical gun.

I really like the action and the placement of the action release. I personally prefer it to the 870 and I also feel like the action on this one is faster. I do appreciate the rotating bolt too. Naturally, this is the system that I have the most experience shooting. Not that I've ever done any real training; I'm just starting out. But I've shot at tons of clay pigeons with birdshot from this gun. I love it.
