Ruger PC9 with the Glock mag well pairs nicely with a G45 or G19. If you prefer .357mag, a 4" 686+ revolver paired with a lever action .357mag works well. I have a Rossi M92 for that config. Bigger? Marlin 1895G in 45-70 paired with a BFR revolver in 45-70. Smaller? Ruger 10/22 rifle and Ruger MKIV pistol.
The .357mag sounds like the best match to your application.
The only problem with Marlins is that they aren’t currently in production. Ruger needs to get up and running, then wait another year for them to work out the kinks.
As another poster mentioned, a .357 lever-action is a good choice.
