I started out with revolvers back in the late 1980s and never thought much of the 9mm at that time. About 10 years later looking for a somewhat compact pistol I picked up a 9mm Sig P239 , the price was good and I really liked the full size Sig P220 in 45 ACP I had owned.
The 9mm really grew on me. Little recoil , mild report compared to the magnum revolvers , relatively cheap to shoot and much more accurate than I had anticipated.
Last year I finally picked up my first high capacity pistol in a Sig P226 in 9mm. It is so remarkably easy to shoot accurately with this pistol. Never thought that I would ever appreciate the 9mm the way I do today.
