New(used) Ruger LCR 357 owner looking for advice

Finally tired of accuracy issues with my LCP Max and traded it in on an LCR. Looking for recommendations on grips , speed loaders and spicy .38 defensive ammo ( ran magnums through it already and doubt I’ll do that again too much) Or any upgrades in general. Mine also came with a lasermax on it while pretty stupid and useless I think it’s cool so any holster advice would be appreciated. Thanks
