I'm looking for recommendations on what kind of red dot to put on my 404 Jeffery. I'd prefer something with a quick detach base. Aimpoint and Trijicon seem to be readily available in Canada.

Unfortunately, that's where I live...

Both of those are probably the most durable mil-spec type mini dots out there. I got an RMR on a 500 NE and a leupold delta point pro on a 505. It matters about the mount and type as well i uses the AHR delta point mount for a CZ550 and the trijicon mount rib mount on a merkel. The swarovski 1-6 zxi illuminated scopes work great as a red dot as well with illumination have several of those if you can find the ee ones perfect for a big bore that might reach out a bit. Not to mention the light gathering of the scope is great too but for short range stopper low profile optic hard to beat a mini red dot

If you want it for dangerous game, I wouldn't trust anything needing a battery. If it doesn't go flat unexpectedly, the electrics may let you down.

At least the Swaro Z6 has a reticle - but if you get too used to the light you might still panic if it goes out.

If you don't believe that, think about why self-loaders have rarely been trusted against dg. In truth they should be more reliable (not subject to African shortstroke) and quicker to recycle if they do misfire; however, the worry about shock to the shooter's psyche is another matter.
