Shots were fired at houses on Farley Road and nearby Vernon Street in the Greets Green area of West Bromwich just after 3am on Saturday.
It was the second shooting in the Black Country and the third in the West Midlands in less than 48 hours after a man was injured in a drive-by attack in Walsall and a teenager was shot at a memorial for gang murder victim Keon Lincoln.
In the West Bromwich shooting, a 44-year-old man was hit in the wrist but police said his injuries are not thought to be serious.
Police tape was put up to seal off Farley Road while forensic officers investigated.
The street remained cordoned off on Saturday lunchtime, with plain-clothed and operational support officers at the scene.
A spokesman for West Midlands Police said: "We’re investigating after gunshots were fired at houses in West Bromwich during the early hours of this morning.
"It happened in Farley Road and nearby Vernon Street just after 3am.
"A 44-year-old man received gunshot injuries to his wrist which fortunately are not thought to be serious.
"We’d urge anyone with any information to contact us via Live Chat on our website or call us on 101 quoting log 369 of 22 January."
