A link on the 329 PD bought to mind that I have a 357 PD I've never even fired. I got it new at a close-out price when they were discontinued some years ago, and with a 329 PD just never got around to using it.
Does any have a 357 PD they have used to any extent? The .41 Mag caliber looks idea for the model - less recoil than the .44 Mag and thicker cylinder so the cases are less prone to stick with heavy loads. I haven't checked out bullet selection, with the smaller caliber and cylinder length you could shoot a bullet with a better sectional density.
