i dont know of anyone making them but thats not to say they dont exist, there seems to be very few aftermarket parts for taurus guns.. i suppose partly because taurus is'nt seen as a classic or collectible gun maker.. and partly because taurus has a waranty that recovers broken parts..
i had seen a kit to extend mag releases though.. it was generic and iirc had a small screw and a plate.. basicly you drilled into your mag release and tapped it for the screw.. then attached the plate with teh screw..
i would imagine such a setup would work and could probably be fashioned your self with some scrap aluminum or something.
and no the beretta mag release is not compatible.
