Seems many need a definition....
Unpretentious....
free from ostentation, elegance, or affectation : MODEST
I have many guns that I have a great affection for and many that I display, meant to impress others. I have a few that have exceptional elegance. But this post isn't about those.
All those guns are off the table..... with this question from the OP....
=================================
For me, a true utilitarian gun, free from elegance would be.... yeah, a couple....
Phoenix Arms .22 with range kit with a longer barrel. This gun is a "Saturday Night Special", but in the right hands.... will dispatch a squirrel at 50 feet on a limb.
Second is my "truck gun".... a Phoenix Arms 9mm. This gun seems to be very unaltered by the dust and grum that a "country truck" would offer and still be very accurate, despite the grunk on it from bouncing around on ranch roads for months on end, under the seat.
