Agreed, definitely not a standard mag. They could have used 8mm rounds, but I do think their mag is taller than ours, thus accomodating more rounds.The Glock pistols that I have used typically employ the double stack magazine shown in the middle of the attached picture. The Major's Thermoptic pistol seems to be a hybrid of a single stack and double stack magazine as shown in the far right of the attached picture. A 1.5 stack? I believe the Sig Sauer p365 magazine does something similar.
