I have another Idea, ammo types. Like a 357 can fire .38s for lower recoil and faster follow ups, but less power. You can use FMJ for punching through enemy cover better, with less stopping power, of jhp for stopping power but less penetration, or jsp to split the difference. Or +P in autos for more power but more recoil. And the P&R model 47 can feed 9x19, 357 38 9x18 etc
