Almost any handgun will do for one style or another. I use a 41mag revolver for field pistol but you can shoot any handgun up to 1.290"case length including 22mag. I also shoot my encore for big bore. It's a reduced loaded 308 since during a match you will shoot between 50 or 60 rounds. Some of the shooters use revolvers to shoot standing but most use contenders, strikers, or similar styled single shot pistols.
If your range shoots small bore then you can shoot any 22lr pistol. The targets are smaller and thinner so only 22's are allowed on this course.
At my first shoot, some of the shooters at my range offered to let me shoot their pistols since I had only brought my revolver. It was like getting together with old freinds.
Good luck in your search.
