I’m 6’. Shoot a glock .40. Not afraid of recoil but want stopping power, reliability, reliability, reliability, and don’t want to shoot through intruder and 3 walls. Is that Rem 870 20 guage?
Rem 870 in 20 gauge is female friendly in use and effect on bad guys. To avoid shooting through 3 walls use birdshot, not buckshot.

12 gauge ammo is more ubiquitous. Especially in a prolonged emergency situation. Just a thought.
