Another pocket gun we spied at the SHOT show were these offerings from Heizer. Dubbed the PKO, Heizer put the .45 ACP to market last fall and have now added a 9MM to their lineup. The PKO is made from stainless steel and the slides are offered in a variety of colorations. On display were gold, iridium, and black. They offer other colors as well. It’s a very interesting design being all metal and it’s nice to look at. It is a little hefty due to the entire thing being made from stainless, however, it feels good in the hand and appears to be solidly built.
