My home defense options:
Colt le6920 (AR15)- Magpul furnature, Ambi safety, Bad lever, BCM large charging handle, Aimpoint ML3 in a Larue lt129 mount, diamondhead BUIS. 5.56 1/7
Works well, light recoil, a bit long.
FN PS90-Aimpoint ML3 in a Tros usa low mount, Side rails, laser, Surefire G2led light.
Super fast handleing (light and small, nimble), no recoil, reliable, but it needs custom ammo if you want to meet FBI recommended penetration in gel.
Glock 23 Too many mods to list. My CCW, so it's allways nearby I grab this or my 1911 before I reach for the above rifles.
Kimber CDP 5" 1911 I don't allways have the luxery of time to inspect bumps in the night. Don't have time to throw on my holster. The 1911, thanks to its safety can be stuffed in my belt a a moments notice, doing that with my Glock would swiss cheese me quickly. For example awnsering the door at night, need someplace to put that gun that I no longer need. IMO, my Glock is only safe in its holster.
Guns I've tried for home defense but will not use cause they don't work for me at all:
12 gauge shotty- overpen, heavy, too long, slow as tar, impossible to reload under stress.
Anything without full ambi controls.
Anything without a pistol grip (you can't shoot a M1 or Mini14 from the Supine position.
Anything that deosn't have sights that can be aimed with out glasses or contacts. Im near sighted, and may not be able to find my glasses, I can use an Aimpoint with out corrective lenses.
Anything that cannot accept a reddot Aimpoint or Eotech.
