[Rick McC.]

Don't know since I've never shot one, but if Rick McC likes his and says it's a great shooter in addition to Caleb's endorsement, then I "think" it must be a great gun. 🤠

Yep.
That said; the Rival DS is a much newer design model, and I believe that Calebs has been around for a bit. Still a good gun though. 👍
