Love it.
The ejectors are solid - really chuck the shells over your shoulder. Also, they're selective ejectors. If you only fire one barrel, crack it open, it only ejects the spent shell. It will slightly "lift" the other shell (or both, if you haven't fired either barrel) so you can easily unload it.
Yes, the opening lever on top is slightly canted to the right.
The triggers have gotten smoother over time. I'm a few hundred (haven't really counted) shells through it now, and the triggers did start off fairly gritty, but have worked smooth as time has gone by. I added a little dab of white lithium grease in the trigger assembly early on, and that made a big difference as well (it was dry as a bone in there when I got it).
I also tracked down a spare choke for it, and now forget what flavour of chokes it takes (other than it's a standard over the counter flavour, picked it up at NoSale Sports) so I could have the top barrel as just a straight cylinder bore. The reason I did that is because I like to be able to fire a flare out of any 12 gauge bush gun - the most likely thing to save you if you get in trouble in the bush is a flare. That requires cylinder bore. Yes, it opens up the pattern a bit, but the top barrel is the rear trigger or "second shot" anyway, and if I'm throwing a cloud of lead at a running grouse, odds are if my first shot doesn't do it, I'm going to need a wider spread to catch it on the second, anyway.
Also, I know I tend to talk up Corwin-Arms a fair bit. But there's a reason for that. Martin is a stand up guy, always stands behind what he sells, and goes the extra mile for his customers.
You'll spend a lot of time looking for someone to say something bad about Martin, and you'll come up empty on that search.
