My MTD Kingston Super 5 - and all MTD Kingston 5ers - has 19mm string spacing. So does my Dingwall. Special mention goes out to my Yamaha BB735a with 18mm which is very comfortable. Lakland 5ers are 19mm too. As are Ibanez BTBs. Sandbergs have adjustable string spacing from between 18mm - 19.5mm I think. Sire basses are 18mm.
These are all off the top of my head so I’m happy to be corrected, but the point I’m trying to make is that basses with wider string spacing aren’t uncommon.
Also, and this isn’t necessarily aimed at you @itu but more for those who may be new to 5 stringers: I’d strongly argue that the shape of the neck, fingerboard radius and string spacing at the nut are just as important as spacing at the bridge. For example, playing an MTD and an Ibanez BTB side by side feels very different despite them both having 19mm spacing at the bridge. The MTD tapers to a narrower nut width than the Ibanez, plus the MTD has an asymmetric neck profile with a bit more meat to it whereas the Ibanez has a wider nut and a flatter neck profile. These things create a huge difference in playability between the two instruments. Bridge string spacing really isn’t everything.
