Personally I have reservations about using steel cased ammo in a gun that was not designed for it - I simply won't do it out of concern for the extractor. Your gun, your choice.
Designed? Please explain how a design might differ for a steel case?
The effect of mild steel cases is negligible to positive. First is they conform well enough to to create an adequate chamber seal, a job all cases should perform. Steel cased ammo from Tula and Barnaul is either brass plated, polymer coated or lacquered to make sure they eject, remember they make military ammo and reliability is important. Since the tensile strength is high, they are less likely to conform to the chamber as brass would and be difficult to extract. Brass thickness and therefore strength is calibrated against the pressure the round will produce and unless the round is overpressure by quite a bit the correct design both seals and ejects. Then same must be done with steel, they but they have 70 years of experience making steel cases so they probably have a simple set of rules to translate dimensions. Also they've been making 9mm Mak since WWII, which is very similar in pressure. Grossly overpressure steel cases might be more difficult to extract but 7.62 and 5.45 rifle ammo have no issues at much higher pressures. Since steel is lighter than brass, then the extractor forces would be less in two ways than brass, lighter case and lesser extraction force.
The LCP has no issues with it.
When only cops have guns, it's called a police state.
