Model 45 Firestar Pistol
The Firestar series is a group of small, compact pistols designed for concealed carry. The M-43 is in 9 mm Parabellum, the M-40 is in .40 cal. S&W and the M-45 is a .45 ACP cal. pistol. They all sport inverted slide rails and cam-unlocking, as well as coned-barrels, but are single action guns with a small frame-mounted safety. All are steel framed and quite thin for their caliber. Parts are mostly not interchangeable between calibers, as the weapons are custom designed to be as small as possible for that caliber.
They are a little too heavy, however for everyday carry for some people. Other mechanical differences include the lack of a firing pin stop plate. To remove the firing pin, the rear sight must be removed (by hammering it off), and the drop safety pull out the top. The trigger is basically that of the 1911 clones like the B series, and retains the disappointing single side transfer bar.
