The Glock 26 is, IMHO, one of the best concealed carry weapons available today.
Here's why:
It fires the 9mm Luger, which with proper round selection is very effective for self defense (more effective than both the .38 special and the .380ACP from similar barrel lengths).
It has good magazine capacity: 10+1 with the standard flush-fit magazine.
And capacity can be increased with the use of magazine extensions or larger magazines with sleeves...
12+1 rounds
15+1 rounds
Considering the G26's size, it is rather light-weight:
Only 26.10 oz. loaded with a standard 10-round magazine.
Although is is not a "pocket pistol", and it is a little on the thick side, this thickness actually contributes to how easy it is to shoot accurately and rapidly.
The Glock trigger is very nice once one becomes familiar with it....a rather light 5 lb pull that is consistant from the very first shot to the very last shot.
And with a very short reset as well.
The G26 is very reliable too.
Glock practically set the standard for reliability in autoloaders.
