The sanctuary is normally full on Sunday mornings.

To my mind, over penetration is a main concern in the event that an active shooter has to be dealt with.

A large slow moving handgun bullet is what I am thinking ?

Consideration :
1. .38 spl hollow base wad cutter bullet reversed with hollow base outward
2. .38 spl fragmentation round
3. .44 spl HP
4. .45 acp 185 gr HP

Opinions ??

Thanks
