I've used an UM #15 Sidekick holster for my SD9VE's for several years. The ambidextrous model adds the mag pouch and a somewhat funky thumbstrap. The ambi model is a bit bulky for me so I went with the Sidekick version. It's a very good fit and a bit less than the ambi version. On the ambi holster you have to adjust a flexible plastic strap and a Cordura strap (both Velcro secured) to secure the pistol.

Best Regards,
