I know about the marlins. Ive never seen one in 45, although Ive encountered them in 9mm many times.
I wouldnt mind having one that took 9mm mags either..Ive got several 59 series magazines in my junk drawer.
Taurus ,45 OSS/DS 24/7 ... twelve round mags, one up the pipe, single double, decocker allows a battery state beside the bed. Laser hangin under the barrel allows off hand accuracy, and wouldn’t have anything else beside the bed waiting for intruders. I have put more than 500 rounds though mine without a problem, shooting everything except reloads. I keep jacketed hollow points in it and the extra mag has ball ammo, for when I want to penetrate to reach something.
