Some of us stick with the factory 5 rounders for the size issue you mentioned. But I'd hesitate to call them ***** quality. The factory ones are tougher than you might think.
You're right, that was poor wording on my part. Its not the quality I disagree with, but the design. A long magazine running perpendicular to the weapon means that when the magazine bumps into something, huge forces are created where the magazine attaches to the weapon. There's no way to brace it, like you can with a tubular magazine, to the barrel.
Then again, coming form a guy whose screenname indicates and affinity for other aged equipment, the "real shotgunners only need this or that" mentality is predicatable.
I keep a Sig for my bedside gun. It's hard to mount a light to a revolver. Technology has its place, but magazine fed shotguns have too many weaknesses compared to regular tube fed shotguns. The only advantage, quick reloading, is mostly unneeded. I don't even think that many LEOs get into shotgun fights where they empty a 7 round tube, then wish they had another large magazine to spray more buckshot and slugs into the air. Also, you can't keep box magazines "topped off" as you go.
Instead of "real shotgunners" I probably should have said "shotgunners who aim and hit things, and know how to thumb rounds into a stable, supported tube".
The Saiga serves a purpose, but seems more like a fad, and an answer to a problem that doesn't exist.
edited to add:
Those who are riflemen for a living don't seem to use the garand, and we have some on this forum, who say they wouldn't take the garand over an AR.
By rifleman I mean people who can shoot at looong range with open sighted battle rifles, quickly and accurately. There aren't many of them who "do it for a living", and those do carry a rifle for a living nowadays are more worried about shooting at close range with high capacity .22 caliber aluminum rifles with vertical handles and widgets that require batteries to work.
Just because someone carries or owns a rifle does not make them a Rifleman.
And seriously, when was the last time you shot your shotgun prone? (Okay, maybe if it's your deer gun, designed for shooting slugs.
I've never fired my pump guns prone, but I shot an 1187 prone while sighting it in for slugs at 100 yards. Once I can afford it, I'll buy a tube fed semi auto, they're great, especially for shooting slugs (its hard to get a good grip on a moving pump, semi autos have solid forends and feel more....solid)
