Steele Wyoming by Ron Goulart

Steele Wyoming by Ron Goulart (F&SF, March 1980) opens with a group of “Outside” down-and-outs roasting a dog for dinner (“Tastes pretty good” . . . “It’s the wild oregano gives it zing”). One the group, Otto, claims he invented Steele Wyoming, a revolutionary guardbot, and proceeds to tell his tale of riches to rags.
This account begins with him rescuing a female friend, Bev, the owner of a pest extermination company called Zapbug (a running joke is that her sonic repellents cause Otto continual problems) from a group of Poverty Commandos and Suicide Cadets who are attacking her mansion. When Otto later tries to convince her to give up her career for him, she says he’ll need to amass greater riches first.
This subsequently leads Otto to create Steele Wyoming, which he then demonstrates to Carlos, a contact at NRA (National Robot & Android):

Carlos chuckled. “He’s very impressive, amigo.”
“Designed to scare the crap out of any looter, rapist, housebreaker or other unwanted Outsider.”
“Steele Wyoming, huh? Catchy.”
“A cowboy name.” I’d gotten butsub on my fingers somehow. Wiping them on the plyocloth, I tossed it aside and one of my little servobots came scooting over to gather it up.
Carlos, slowly, circled Steele Wyoming. “I assume he’s lethal as well as frightening?”
“Tell him, Steele.”
“First off, let me say howdy, Mr. Trinidad, sir,” drawled the big android in his rumbling Old West voice. He reached a huge horny hand up to tip his highcrown stetson. “I kin be lethal or I kin merely stun varmints. Depends on how the nice folks who owns me wants the deal to go down.”
Carlos laughed, pleased. “He’s terrific, amigo.”
“What I figured,” I said while Carlos stood gazing up at the seven foot tall cowboy android, “is that to a great many people in America, even in this year of 2020, the cowboy remains a symbol of honesty, dedication, law and order.”
Steele adjusted his hat on his head.
“That is surely true.”  p. 86

The rest of the story (spoiler) sees the homicidal results of Wyoming’s trigger happy attitude1 (starting with a noisy subrock millionaire neighbour, and followed by the three policemen who see Wyoming dumping the body). Further complications result from Bev’s infidelity.
Amusing stuff.

1. One wonders if Wyoming’s lethality was modelled on Clint Eastwood’s movies of the time (the spaghetti Westerns and Dirty Harry series).
