My belgian challenger is the most reliable & accurate pistol I have ever used. They were made for high velocity ammo, but if it has been used very much you should change the recoil spring. The springs are cheap if you can find one, If not Wolff springs makes a kit for the Colt Woodsman that should work. I like CCI minimags & velocitors in mine. Mine has the 6 3/4 barrel, & I would like to find a 4 1/2 inch barrel just to try it.
