I have one, it has the magnetized bolt head and full length mag, but still has the cross bolt safety and cylinder bore. I've been looking for a tang model with screw in chokes and a full length mag, but as mentioned, they are not to be found.
It has to be one of the most fun guns I have ever used. I originally bought it for doing rat control work. I needed a high capacity gun, and since semi's are limited to 5, the 9410 with the 9+1 capacity seemed to fit the bill. I was lucky enough then to find one within about 3 months, the only full length mag I've ever found for sale. They were already out of manufacture by the time I decided I needed one.
I bought it for work, but have since used it for all kinds of stuff, it is just a blast to shoot, I just wish I had the invector choke system, as I'm really limited on range, which takes a lot of clays shooting out of the picture. On rats under a bale stack, it's nearly perfect, and for flushing pigeons out of granaries, more choke would be nice, but as long as I'm quick I can get lots. I use primarily 1/2 oz of #9's.
Downsides are that the fiber optic front sight is crap, the fibers keep falling out, so I finally replaced it with a steel front sight off a 94 after the 3rd fiber broke. The back sight loosened off and I lost a screw, but fortunately I still had the plastic rear sight, so I suggest a little locktite on it would be a good idea. I did wear out the loading gate spring, it was still functioning, but had very little spring left in it, but it wasn't too hard to change out, and I suspect that it's no different then any other 94 for wear, it lasted about 4000 rounds fired, and I would think easily another 1000 rounds through the loading gate, loading and unloading while pigeon hunting. The receiver is like all later 94 receivers seem to be for finish, and doesn't hold off the rust that well, so make sure to keep it well oiled. I ended up putting a leather wrap on the lever, it wasn't too bad, but when I was putting a 100-200 rounds a session through it on multiple hand thrown clays, I found the bare steel to get hard on the knuckles.
Feeding I've found to be exceptional, very rarely a bobble, even with hulls that have been reloaded multiple times. Probably at least 95% of the rare feeding issues are operator error.
It's one of the funnest guns I own, I can understand why there are none on the market, anyone who has used there's isn't about to get rid of it.
