Remington is the McDonalds of the gun manufacturer's, I think total junk most of the time. The only thing I've bought from them recently is a 1911 which was OK, when I put a new spring in it. Friends that have bought Remington have been burnt. I bought a Remlin Cowboy 1895 because it was on special at KTP, and it was satisfactory...not perfect or as good as older models made in New Haven. But better than the 2012 stuff for sure. I would not buy a new Marlin online without looking at it....too many turds in the punchbowl.
Smith, Sig, and Ruger are the Ford, Chevy, Dodge of the gun producers and try the newest things to get products sold, usually lacking in design or quality to do it. Although, I've had very little issue with Ruger or Smith 1911's, recently bought in the last few years. And no issues with Ruger or Smith plastic semi auto's either. Friends have Sigs and have had no issues. I can't comment on revolvers, have old ones. I do think a lot of issues are overblown on the internet with these makers....most of their products are good from what I've experienced.
There are makers that make a quality product though, usually you have to pay a bit more for it.
Browning, Dan Wesson, Winchester, Beretta, Glock, etc...are a step up in quality, and I think produce products just as good as the old days.
Then there's some Turkish made products like the Canik's, etc...finish quality isn't the best...but the guns run like mad, and cost half of what others do. I like what Ruger does to try and breach into this market, with their ugly but American made products.
I'm willing to try and support it.....when I need a truck gun or tackle box gun that doesn't need to be pretty or fancy, it just needs to work.
