just poking around the internets for mag options for the 938. factory 6rnd mags run just south of $40. there are promag made mags for around $20, but I steer clear of that manufacturer. I found this write up: Kimber Micro 9 vs Sig 938: in depth review and range session - Topic it really...

next to my citadel 9mm :) the safety is positive and the trigger is better than I deserve!
