I think its awesome, you lucky dog, TSW rails being the same cut as PCs , you did exactly what you needed to fit it. I was back at Armorers school and was hanging out in the P/C, watched them tapping slides back and forth, with compound, on frames, with the slide backwards, till it fit. Original gun must have been stolen and the frame/serialized part destroyed, so what a great save. Closest thing to a Mexican Spec Forces 5906, in a 5", most of us will ever see. I replaced the trigger bar in my 4006 with one with a trigger play spring it took all the slop out, but really not needed. Beretta dont have one. Please let us know how it shoots....
