I have two of these in two different sizes. One for my Glock 21 mags and one for my Springfield XD Sub-Compact 40 mags. Both are well constructed and do the job.
Pros: Good item for a good price.
Cons: When the screw is tightened to hold my Springfield XD 40 mags, the screw pushed a bit through the back of the pouch leaving the jagged tip of the screw rubbing against my belt. Solution was to put some 100 mile an hour tape over it.
