No, steel cased ammo is fine. Most Tula and Wolf is actually the same stuff, out of the same factories. Different label/importer. Tula tends to be a bit cheaper because Wolf has customer service and supposedly it's easier to get them to take care of customers if there's a problem.
All manufacturers have periodic recalls, and if you look hard enough, you can find stories and pictures of blow'd up weapons from faulty ammunition from every manufacturer.

Hornady sells steel cased training ammunition now. Steel cased ammo has a reputation for being hard on guns, but it's really not deserved. It's not high carbon super hard armor-plate steel; it's soft mild steel. Fear of extra wear on guns probably isn't warranted.
It used to be that the Russian steel cased ammo was coated with a laquer that got hot and gummy and tended to cause stuck cases, especially in AR-type guns, but for years now it's been polymer coated. If you switch back and forth between brass and steel cased ammo, you may wind up with a stuck case because the steel cased stuff tends to be dirty, it doesn't expand to seal the chamber as well as brass, and so the chamber gets more nasty more quickly. Follow up with a brass cartridge in that dirty chamber, you're more likely to get a stuck case.
If you have an expensive match <1 MOA rifle barrel, it makes no real sense to be shooting cheap 4+ MOA Russian import ammo out of it. (It makes no sense to be shooting brass cased Federal M193 out of it either.)
There's absolutely nothing wrong with steel cased ammunition. With Wolf/Tula you're getting cheaper, dirtier, less accurate ammunition. If you shoot twice per year, saving $1.50 on a box of handgun ammo is no big deal. If you're on a budget and shoot more though, $30 to $100 per case adds up.
It's just my opinion, but to me, insisting on shooting premium brass cased ammo out of Glocks at 7 yards isn't all that different from putting premium gas in a subcompact Hyundai used to commute to work.
