I was looking for a laser too for my PT-145 (picking up tommorrow) and was told by armalaser that they are coming out with one for mine in a few months. I didn't ask about the 24/7 or even if it will fit on both. Saw their ad in this months american handgunner. They also have a site www.armalaser.com and was told the PT-145 version will look like their Kel tec Pf9 version. Might want to ask them, I spoke with Nick.
