Everything they make is "Express" unless it is a "Police" model. The Tactical series guns are also Express models. I wouldn't say the bulk of their product line is "crap." I'm curious now...what was your bad Express experience?
I have an older 870 Express, bought in 1995 or so. It even has the metal trigger guard/housing unlike the newer ones. My two points of contention with the gun, from a standpoint of serious use are...
1) The extractor is MIM. Can I replace it? Of course, but it didn't come with a machined one from the factory. Will I ever break it? Probably not. But I am looking at it from a home defense view and if an MIM extractor was completely capable they'd be using them in the police model as well, not the more expensive machined versions.
2) The rust issue. I do not abuse my firearms, and have had my share of less-expensive firearms. Only two have ever had rust issues. One Mossy 500, which rusted a little on the unfinished bolt (expected), and then the 870 which rusts on all metal surfaces unless they stay dripping with Hoppes oil or CLP. If the shotgun gets dry, both the parked and blued surfaces sheen over with rust (except for the aluminum trigger guard). It does this sitting in a safe with a relative humidity of 22-25%. The unfinished hammer also rusts. Once, I shot it and cleaned it, oiling the entire gun but forgetting to rub some on the trigger. Weeks later, I pulled it out again and the trigger was a puffy ball of brown. It was not just surface rust, and is still pitted from where I had to scrub it off. I can't rely on this gun for SD because of this issue. I might not have time to examine the whole shotgun for rust that may implede the functioning of it if I need to grab and go. I have established that it's not just mine either. I have one friend with one that does the same thing, and also two at work that do.
It's a great for field or any other use where it's not life or death if it doesn't go bang. But for something I may really
need to work, it's not up to par. I suppose I should clarify and say that it's crap when it comes to serious use. But, that's just an opnion of course, and if your Express models work for you more power to you, and know that I envy you for having one that doesn't give you any issues.
