So much fun!
I also like the idea of having several weapons that use the same common easily obtainable affordable round.
I have a PC9 with a 50 round “boom stick”. Also takes Glock mags so it pairs well with my Glock 19.
Also have two Taurus public defenders one loaded with 000 buckshot and the other with #6 birdshot.
Well prepared in the home defense department.
