GLOCK G20 Gen 4 10mm
Glock 20 Gen 4 10mm
This G20 offered the most DIY customization, was the softest shooter and was accurate, plus the price was less. Also, it was the best suited for concealed carry.
The G20 Gen4 is the latest evolution of Glock pistols with replaceable back straps to fit a variety of hand sizes. Testers liked the ability to swap back straps; four sizes came with the pistol or the pistol could be used without a back strap, so five possible grip configurations are available. Some testers with smaller hands thought the Glock still felt a bit chunky in the hand compared to the other pistols.
The accessory rail on the G20 Gen4 was smooth, which made it easier to holster. In fact, testers felt the G20 was the most comfortable 10mm to carry due to its light weight of only 39.5 ounces loaded. The G20 also has the three safety features: trigger, firing pin, and drop safety. This is a very safe pistol.
The sights on the Glock are serviceable, but were the least liked by testers. The plastic front used a dot with the plastic rear sight outlined. The target picture was fine, but we preferred the sights on the other two pistols. Glock sights are easily replaced ($10-$32), and there are numerous aftermarket sights which still cost more, bringing the Austrian entry in line with the cost of the RIA but still well under the SIG.
The trigger was typical Glock, with a pull weight of about 5.5 pounds. It is a trigger we have come to accept or enhance with drop-in aftermarket trigger kits. The Glock we felt was more easily customized by the owner than the RIA or SIG, and that was a plus. In fact, our test pistol was owned by one of our staff, who also had an extra 6-inch hunting barrel ($150), which added to the total cost of the pistol, yet still put its total cost well under the cost of the SIG and near the cost of RIA.
The longer barrel allowed the Glock to generate more velocity with the 10mm ammo, averaging about 30 fps extra per load, but when we reviewed the range data, the Glock data was still lower than the other two pistols, even with the addition of a 6-inch barrel. Data still showed the Glock lagging behind the velocity of the RIA and SIG. We were had hoped the 6-inch hunting barrel would eke out more velocity, but it essentially leveled the velocity playing field between the pistols, while adding length to the Glock.
At the range, we found the Glock provided the second-best accuracy, on average, of the three pistols. With the defense loads — Federal Hydra-Shok and SIG V-Crown — the best 5-shot group was tied at 0.7 inches. Testers felt the Glock was also the softest shooting of the pistols, hands down. The polymer frame of the G20 flexed to help absorb recoil, while the slightly fatter grip had more contact with the palm, so recoil was more spread out.
Our Team Said: The Glock 20 was a soft shooter. The girth was larger, but manageable, and the trigger was a Glock trigger that could be improved with an aftermarket kit. Plus there are numerous other parts to customize the pistol.
