The Lawman III is one of the new design Colt DA revolvers; it uses a coil mainspring (hammer spring) which is fairly easy to replace. Check www.gunpartscorp.com for the part.

But before doing so, how about the ammo? Is it fairly fresh and has it worked OK in other guns.? Most of the time, misfires are due to the ammo, not the gun. (Don't be deceived by the seeming shallow dent in the primer; the dent in a dead primer looks shallow because when the primer fires, its metal flows back around the firing pin, making the dent look deeper than it is.)
