If you guys are hand-loaders, just make some dummy rounds w/out powder nor primers. I fill the primer pockets w/automotive gasket sealer for the hammer to hit. Also easy to spot compared to a live primer. Tried painting the base, but it rubbed off against the recoil shield. I prefer dry-firing with dummy rounds, 'cause the bullet weights make the trigger pull the same as a fully loaded revolver.
