New L9CZ pistol has wrong magazine capacities

The new L9CZ pistol has the wrong magazine capacities. The default 16 round mag only holds 15 in-game, and the extended mag claiming to hold 26, only holds 20 in-game.

I genuinely don't understand how this keeps happening. Is it that hard to track one number and set it correctly? So many guns have this problem, and I guarantee it's a 1 minute fix.
