Yes, but if you shoot exclusively .38 +P out of it, which many would recommend for SD, wouldn't the cylinder eventually suffer from gas cutting?
The only times that I've ever even heard of gas cutting or flame cutting being an issue is with magnum cartridges firing medium-to-lightweight bullets or defective alloy frames. Even in such cases, flame cutting is usually self-limiting and occurs in the topstrap above the barrel/cylinder gap rather than in the chambers themselves. A .38 Special or .38 +P should not be particularly prone of flame cutting because, unlike magnum cartridges, it's not commonly loaded with large quantities of slow-burning powder.
