Anyone own a Iron Horse Sentry 12 shotgun?

[Greenhorse six]

The metal feed lips are clipped on the outside of the plastic mag body ?

Really like the look of these and the mag fed capability but there's some mixed reviews.

Recently read about someone's mag falling out when loaded with 5 or 8 shells.

Any feedback is appreciated.

Kinda late to this post, but I do own a Sentry 12 shotgun. Its very light and kicks like a mule with 2-3/4 slugs, which is the majority of what I shoot. Buck and birdshot are like nothing in comparison.
I added some metal flip up iron sights, got 2 extra 8 round mags and coupled them together. Modified a semi auto shotgun coupler or was it for an ak47 mag?? Cant remember
Using a grinder to get these fat boys to fit together but it came out sick. Very tactical looking and legal in NY state. Just missing a light/ laser combo.
Overall the gun is pretty simple.. Pump action loads fine unless you shoot like 100+ rounds through it than maybe the barrel heat makes pumping it harder and harder.. even adding lubricant doesnt seem to help.. just have to wait until it cools down. It was surprisingly accurate at range too very easy to shoot. Other than slugs blasting you back, I'm 200lbs and it jerks me pretty good .. I mean I dont know what else to say its a decent little shotgun for home defense or messing around I'd say.. pretty reliable.. the mags never gave me issues, they do feel sort of cheap but they work and that metal piece never fell off for me. The mag did fall off once bc I didnt slam it in all the way, only ever happend once but that was user error not the mag design. Trying to get pictures up, my first time using this.
