Â­Steel is iron that has most of the impurities removed. Steel also has a consistent concentration of carbon throughout (0.5 to 1.5 percent). Impurities like silica, phosphorous and sulfur weaken steel tremendously, so they must be eliminated. The advantage of steel over iron is greatly improved strength. The open-hearth furnace is one way to create steel from pig iron. The pig iron, limestone and iron ore go into an open-hearth furnace. It is heated to about 1,600 degrees F (871 degrees C). The limestone and ore form a slag that floats on the surface.

The Tactical Solutions conversion is a well-built, all-steel slide and barrel that replaces the top end on a Glock. Installing the TacSol unit is as easy as removing the slide and replacing it on a Glock, and takes only a few seconds to do so.The unit ships with either a ten or a fifteen round magazine.he bullets in that ammo are a full 40 grains, and I think that really helps reliability. Pricing on the TacSol TSG-22 units starts at $395 US as of the date of this review. There are cheaper 22 conversion units available, but I have found none that run as reliably as do these TSG-22 units.
