http://www.glock.com/compensator.htmAlthough they are available in different frame sizes and caliber's, they are similar in one respect: they all have ported barrels. Known collectively as the "C" models, these include the 17C, 19C, 20C, 21C, 22C, 23C, 24C, 31C, and 32C.
All these new compensated models, except the GLOCK 24C have the same features as their counterpart non-compensated service pistols except for the addition of the barrel ports that face out and exhaust through two vents cut into the top of each slide. The GLOCK 24C is the longslide competition pistol in .40 and here the four ports are placed on top of the barrel to vent through the open area at the top of the slide.
Shooters who are recoil sensitive will especially appreciate the GLOCK "C" models. They are also useful for young and beginning shooters
