I recently looked at the AIM-9J/N/P and AIM-9L/M versions in 1/72. What many manufacturers overlook is the difference in size of the rear wings, those of the L/M being larger. Hasegawa for example overlooked it in its Aircraft Weapons set #3. The front fins are often quite misshappen, except in the most modern models. The one I liked best was the AIM-9L included in the Revell-Germany F-16 kit, but I didn't measure it.
