Ok, I'm a lurker on this site, and I've been reading the threads on which shotgun to buy. Seems to be a Chevy/Ford type thing, but I still am looking for particular advice. I would like to get into 3-gun and/or sporting clays, but I have a bad shoulder on my dominant eye (left). What I'm looking for is a semi that will be easy on the bad shoulder, reliable and ready to go out of the box. I'm guessing it will be a gas gun, I'm open to a 20 gauge (though most seem to be lighter than the 12s), and I'd prefer something with good availability of parts (been down the path of not being able to get parts with handguns before - not fun). Spending money is not an issue if it is well spent (like when you buy riflescopes). I want a good trigger, because that always seems to be the thing you have to send the gun off to get worked on. If it needs a tube extension, that's OK. Being able to change barrel lengths is a plus, but not necessary.
So what are your recommendations?
