Series of stories. Main character is a professional bass player in a band that he has mostly left or been kicked out of. He had the rights to merchandise and the band's logo I think. Lived in the top floor of a renovated warehouse in a mid to larger size city. Maybe Cleveland or detroit.
In the warehouse loft apartment he had self done archery range that he could practice on.
In the 2nd or 3rd novel they find a pistol in the elevator machinery room. I thought the name of a latter book was the case of the polish pistol, but I cannot find that book by searching.
Any of those ring a bell?
