Both revolvers are built around the 327 Scandium alloy frame
The 2" 327
Is a Performance Center offering, product code 170245, it has a 2" barrel and a fixed sight channel milled into the frame, the cylinder is titanium and cut for moon clips.
The 327 Night Guard
Is offered from the production side of Smith & Wesson, product code 163422, it has a 2 1/2" barrel and is milled for adjustable sights. However it is wearing a Cylinder & Slide Extreme Duty U-notch rear sight with a front Tritium Dot from XS sights, the cylinder is stainless steel coated with IonBond
Where to find a 327 Night Guard . . . Look in all the same places that we look for any revolver that has been discontinued for 10 years . . . Auction sites, gun shows, small local gun stores
Which is easier to carry? Probably the 2". but I have not carried my 2" 327 since getting my various Night Guards. I appreciate the better sights.
The easiest thing to carry is not always the best choice to carry.
