Glock GL21C .45 ACP

Read Gun Tests Rating and Recommendation

With porting you do not have to be a muscleman to handle a full-size gun chambered for a bigger caliber. The tradeoff is more noise and some concern about avoiding the gas ports.

All Glock pistols designated with the letter "c" feature gas ports positioned 45 degrees from the bore line. This helps prevent the blast from distracting the shooter and keeps the face of the front sight from being covered with debris.
The GL21 and GL21C each weighed in at about 27 ounces. In both of the guns, most the weight was in the wide, beefy slide. The frame (shown at right) was feather light in comparison. Primary contact with the slide was on the metallic inserts seen front and rear along the rails.
