At 1 time I owned 2 Rugers, a snub sp101 and a Redhawk 357 both with the hybraport package done by Jack Weigand. They had, in tandem conical ports along the top of the barrels, similar to the pic of that Taurus 45acp. While shooting the sp101 at an indoor range, the overhead light shattered at the exact moment I fired. COINCIDENCE or escaping gasses???? A retention position, or squatting down behind cover shooting upwards (or ANY other position) that may get those ports in your direction, would be a bad thing, IMO.
OTOH TEHO, & you may look good with some "sunburn". Probly (???) a non issue with a magna port that directs those gasses to the sides.
