The first and second photos are caliber 22LR, were designed to be used with silencers. The third and fourth photos are 9mm. It's a popular caliber in Beretta92, MP5, Uzi, etc. The 9mm model was perfect for close quater combat and various urban situation. Some claimed the rotary magzines have feeding problems. It's due to the magzines were made by polymer materiel, as temperature increases, it would tend to deform after prolong usage. It cane be overcomed when changed into aluminum.
