I can compare against Rogues and Derringers, but never had an RM2...
Hellboy is a great suggestion for WAY more airflow, and you could always close some of it off if needed. Another huge air rda would be the Dark Horse if Chowderhead has any left, though its a bit on the tall size as well.
For airflow similar to a Derringer wide open, there's the Freakshow. It has bottom air slots. Rogue and Manta wide open are just slightly more restrictive wide open compared to wide open Derringer. There's a REMatty that spanking new (haven't gotten mine yet) but looks to combine the best features of a Rogue and Derringer.
I hope this helps a little bit! I like them all bit keep using this Derringer as my daily driver. When I'm out and about will often take the Rogue with me since it just flat won't leak.
