Bubbaman, as a HD gun, the 410 Saiga has two strikes against it from the get-go, and they apply to any .410-bore autoloader.
Strike One is the size, most folks prefer a gauge larger than a .410-bore in a HD gun. Yeah, I know, you hear a lot about the new special .410 HD loads; but, they are intended for the Judge revolver. A .410 is a pretty hot handgun load, but it's lightweight shotgun load. Most would select a 12-ga for HD with the 20-ga a distant second choice.
Strike Two is the action type, most folks want a very reliable gun for HD, and prefer a pump action over an autoloaders. I don't know why, a pump is just as likely to be finicky about ammo as an auto. I've read several recent threads about Remington 870 Express models having extraction problems, not so with the Remington 1100 auto.
Most competitors, myself included, don't use an autoloader for match work because they've lost too many targets due to autoloader FTFs. They prefer the O/U -- drop one (or two) in, and if the action closes smoothly the probability of the gun shooting is awesomely high. Yes, there can be occasional trouble with the selection mechanism in a single trigger O/U -- selecting a double trigger HD gun eliminates that possibility. That's why some prefer a coach gun for HD -- they select reliability over a pump's larger magazine capacity. (Some shooters, well trained with a double gun, can get off 4-shots very quickly.)
If you hear something go bump in the night and your choice is between a 410 Saiga and no gun, it's a no brainer. However, given a choice, it wouldn't be my go-to gun for HD.
