I find it very interesting that the polymer framed PPS and the steel framed MK9 Elite weigh roughly the same.
Something to consider. For me, at least ...
A 9mm operator with a full rail? Never seen one before. Does that thing have any recoil?
That's how I felt about my P7M8, even in a top of the line Milt Sparks holster and a good belt. I have three 9mm carry guns. A G19, Kahr CW9, and a lightly customized Kimber Pro Ageis (light weight commander size). Of the three, I prefer to carry the CW9, but the most "shootable" is the 1911...so the 1911 gets carried the most. If I had it to do over, I would take a serious look at the Dan Wesson Valor.It's rather heavy for its size, and doesn't balance all that well in a holster.
Hhmmm....Taurus PT-99, worked over by my resident gunsmith.-
