Yesterday I went to my local range and rented a Gen 3 Glock 26 and a Smith & Wesson M&P9c. I shot 50 rounds of Remington UMC 115gr 9mm ammo through each one of them. I was able to shoot tight groups with both pistols from 10 - 25 yards, the M&P9c had slightly better ergonomics, the Glock 26 was smaller and lighter, the M&P9c has more mag capacity (12 vs. 10) with the standard magazine, the M&P9c is aesthetically superior to the Glock 26 and I liked the Glock 26 trigger over the M&P9c. Therefore, it all comes down to the specs (size, weight, capacity, etc.) and price. The Glock 26 is $200 - $300 more expensive than the M&P9c, but the Glock 26 is definitely easier to conceal and that is my # 1 reason for my purchase.
Therefore, I have chosen to buy a Gen 4 Glock 26 and join the dark side!!!!
