I have a couple of G26's. One is 10 years old and has been used to fire more than 10,000 rounds of assorted ammunition over the years (issued 147gr JHP, 124gr +P GS and 127gr +P+ T-Series as issued loads, as well as an assortment of other standard pressure, +P & +P+ rounds for training & practice). It's received normal maintenance and periodic parts replacement of wearable parts. It's never failed to feed, fire, extract & eject a single round. (I can't say the same for my G27.)
My second G26 is a brand new OD model produced a couple of months ago. It's had slightly less than 200 rounds fired through it thus far, but it's been fine and I expect it to provide the same service I've received from my other G26.
The G26 is not my "favorite" small 9mm pistol, but it
is my favorite Glock from among their model line. I've handled and fired most of them over the years, and I also own a G27 which has seen more than 10,000 rounds fired through it, as well. If I had to choose between the G26 & G27, I'd choose the G26, no question ... but that's me, and I'm sure other folks will feel differently. Different strokes.
I'm an armorer for Glock, as well as for a number of other firearms commonly seen in LE/Gov service, and I have complete confidence in the G26 to optimally function as intended when good quality factory ammunition is used by a shooter who uses good grip technique/shooting skills and maintains the gun as recommended by Glock (meaning proper cleaning & lubrication).
Just my thoughts.
