In Mexico, two American cowboys, Johnny Darrel (Johnny Mack Brown) and Dick Martin (Julian Madison) join a poker game to try to win some money and help out their buddy, Oscar (Sid Saylor).  When they discover that cantina owner Manuel Mendez (Ted Adams) has rigged the game, a fight breaks out.  The lights turn off.  In the darkness, several guns are fired.  When the lights come back up, Dick is dead.  Mendez convinces Johnny that he accidentally shot his friend in the fight.  Guilt-stricken, Johnny tosses aside his guns and returns to Texas.

Johnny has sworn that he will never shoot another gun but when he’s hired to work at a ranch owned by Joan Williams (Claire Rochelle), he finds himself in the middle of a range war between Joan and Brace Stevens (Dick Curtis), with Mendez also making an unwelcome return to Johnny’s life.  Even after Johnny discovers the truth about what happened that night at the cantina, he doesn’t pick up a gun.  Instead, Johnny fights the bad guys with lassos and plates.

Guns In The Dark is only 54 minutes long and it features actors who will be familiar to any fan of the old B-westerns.  Sidekcick Sid Saylor’s stuttering schtick gets old quickly but Johnny Mack Brown is as likable as always in Guns In The Dark and he comes across as being an authentic cowboy even when he’s not carrying a gun  Given that this film features even more horse chases than the typical Johnny Mack Brown b-western, it’s good that Brown is so convincing.  What isn’t convincing is how stupid Johnny Darrel is required to be in order for him to fall for Mendez’s lie in the first place.  I appreciated the change of pace from Brown just using a gun to stop the bad guys but I wish the reason behind it had been more convincing.  This isn’t one of Johnny Mack Brown’s more memorable westerns though, as always, it’s easy to see why he was one of the early stars of the genre.
