Split leather is leather created from the fibrous part of the hide left once the top-grain of the rawhide has been separated from the hide. During the splitting operation, the top-grain and drop split are separated. The drop split can be further split (thickness allowing) into a middle split and a flesh split.
Excruciating pain. It all depends where the bullet enters. A person shot in the brain will likely perceive no pain as the trauma usually renders them immediately unconscious. A bullet entering a limb such as a leg is initially perceived as a hot sting. Within 20 minutes a throbbing, pulsating pain is experienced.
Trigger Feel. Trigger feel is an important quality when firing any gun, but this is probably the greatest difference between hammer and striker fired weapons. Many shooters feel that striker fired pistols often have mushy, or soft triggers.
