There should be a lot of holsters available for your gun, but it's often tough for the holster makers to keep their websites up to date with all the current gun models. It often seems the leather holster makers are a little slower updating their gun availability lists than the kydex makers. Just because they aren't shown on the makers lists, doesn't always mean they aren't available. You may need to call or email and ask. The ones I listed specifically show your pistol in their available guns list.
Being a lefty shouldn't be an issue. Nearly everybody that makes a holster for your gun will make a left hand version.
