Which qualification course? for Expert Pistol ribbon/medal? For that, check with the folks in the armory, or with your personnel officer. If things haven't changed too much since I was in, the answer will be in the Small Arms Marksmanship Manual, NavPers 93863, complete with NSN, which might be 6920-00-554-5054, which is simply an NRA 25yd TF/RF bullseye target. But do check the manual - things change .
If you are talking about some other kind of qualification, ask the person who issues it.
