WTS a Scherer glock 23 magazine, holds 29 rds. I am told it fits any glock in 40 S&W, but checlk for yourself, I am not the all-knowing glock guru. What I can tell you though is that this magazine is like new,used once or twice in my G23 for the fun factor, functions smooth and flawless, only selling because I sold my Glock 23 recently and as such I have no use for it. 50 bucks shipped first class and fast seems fair, if not, show me where one is cheaper and I'll work with you. Feel free to ask any questions. Thanks and take care.
