I love the 686 +1, 2.5" (upper left). I'll have to settle for my 627-5 for the time being.
The 629 (lower left) is cool with the fluted barrel but loses its intimidation factor with the clear orange Lego on the front.
The M986 and M929 have a wide enough gap between the cylinder and frame to dangle a snack by a string for convenient snacking and shooting.
Despite this gap I'd still love a revolver in 9mm, as ammo prices keep on galloping higher and higher.
That gap totally killed any desire that I had for this piece. It seems like a 9mm was an afterthought, built on leftover .38 spcl frames.
