Most SNS have quite uncreative model names. Usually, the prefix describes the gun or it's maker in some way and the suffix is the caliber. For example, the Raven P-25 could be decoded as "Pistol, caliber .25". Or the Hi-Point C9 would be "Compact, 9mm" as their other offerings are certainly not compact. The Jennings J-22 presumably got the J prefix because, when the firm started, Bruce's dad George was already using the P prefix. When Jennings started making centerfires, they gave the .25 Auto pistol the name "Model 25", presumably because of the caliber. However this doesn't explain the model 38, 48 , 58 and 59. When Jennings rolled out it's double stack 9mm they wanted everyone to know it, with "Jennings Nine" in big print on the slide. I wonder if this was an unspoken effort to market the pistol on the street, as rap music was filled with references to the "nine" at the time.
There are a few deviations out there. The larger Hi-Points use model numbers that sound like ammo descriptors, i.e. JHP and JCP. Sundance used the name "Point Blank" for it's derringer which is actually a pretty good name for this sort of gun. Of course, FIE continued to use the Titan name on a variety of guns, including the domestic versions of previous Italian imports.
