The Glock G20 is one of the few pistols chambered in the powerful 10mm AUTO cartridge still in mass production today. In fact, the only other 10mm pistol that is currently being produced in large numbers is the Colt Delta Elite.
There is little in the way of new innovation where the Glock 20 is concerned. It's overall design is shared with the more popular G17 and G22 models with the big difference being the performance the gun provides. That performance, however, is more a product of the 10mm cartridge than any factor unique to the G20 service pistol.
The 10mm is often referred to as “the greatest handgun cartridge never known” because of the massive amounts of energy that the round is able to transfer to a target upon impact. Transferred energy is directly related to so-called “stopping power” and the 10mm, properly loaded, is rated just below the .44 Magnum where stopping power is concerned.
This massive amount of kinetic energy is mostly due to the speed at which the 10mm round travels. Full-load rounds such as Buffalo Bore 10mm ammo can consistently shoot at 1,350 fps at 25 yards. The speed of sound for a 10mm cartridge at sea level is 1120.27 fps and the round does not fall below that level unit around 136 yards. This means that the round is traveling faster than the speed of sound for a significantly longer distance than the effective range at which a target would be engaged.
As the 10mm is known to develop a lot of recoil when fired, the round is not favored by either police or military forces in the United States. For this reason more than any other, the 10mm is not a very popular round and the ammunition is usually on the expensive side. The Glock 20 service pistol is made primarily to meet the needs of a few European law enforcement agencies. There is also a dedicated group of 10mm enthusiasts who flock to the G20 because of its quality and reliability in addition to the fact that there are few other choices currently available.
The Glock 20 has a magazine capacity of 15 rounds. If an initial extra round is carried in the chamber that brings the total load out of the gun to 16 rounds of 10mm ammo. With an average of about 700 ft/lbs of energy being transferred to the target at 25 yards means that the G20 service pistol carries about 11,200 ft/lbs of stopping power when fully loaded. It is this impressive figure that makes the Glock 20 a serious contender for the title of “most powerful handgun in the world”.
All other features of this Glock service pistol remain in common with the others in the lineup. While the physical size of the gun is slightly larger to accommodate the longer cartridge, the Glock safety systems, sights, finish, grip texture, and maintenance methods remain the same.
Reviews of the Glock G20 service pistol can be found below. If you have one of these pistols yourself, please share you own insights with others here by writing a review of your own. Of specific interest to others will probably be related to how well the gun stands up to extended use and how well one can adapt to shooting the more powerful 10mm cartridge.

KaBoom! Glock's unsupported barrel for a cartridge is a major problem, especially when this cartridge can generate upwards to 37500psi MAP. I have owned two G20. First G20 (Gen2) ended with a cracked frame and damaged magazine after a KBM! catastrophic failure event. Glock does not seem to like to admit fault and is not particularly interested in hearing about it and gave me the run-around for 6 months. They even threatened to sue for defamation if I tarnished Glock's reputation! Four years later I did purchased a G20 gen3 and installed a KKM barrel before a shot was ever shot through it. Read More
I've just purchased the G20 SF recently, and now just waiting until the 10 day waiting period is over. However just a few weeks ago I went down to the range with one of my buddy, and rented the G20 full size not SF. I don't no what is all the fuss about the excessive recoil like they were saying, after putting about 50 rounds down range I fell in love with this gun. As for recoil it's no more than like shooting a 45acp in my opinion, felt very similar to shooting a 45 Springfield XD. Read More
I've owned my Glock 20 for close to 20 years and and would consider it an excellent survival weapon, it's not a target pistol. I use my Olympic Hammerli or Benelli target pistols instead. I'm a small person, 5' 6" 190 pounds with small hands. Other smaller calibers may be easier to shoot, but by definition of the caliber, lower energy, lower mass, lower stopping power. Although I don't shoot it often, I'm quite comfortable with it. The secret to my managing this weapon is 1) a firm two hand grip, 2) recognize it has a kick, but have a "mind set" even in combat to ignore the recoil and report, 3) let the weight of the weapon bring it back to firing position, don't try to physically whip it back into position, as one can over compensate like oversteering a car, 4) focus on placing the shot well and forget the noise, recoil and all the negative things people will say about the Glock 10 mm!

I don't know why the FBI solicited the development of the 10mm auto cartridge only to back out later because some smaller and more sensitive FBI agents were afraid of it.I shoot 22lr,22mag,38 special,357 mag,9mm luger,357sig,9x25 dillon,40 S&W,10mm,44 mag,454 casull and 500 mag.I'm 6' 225 lbs,not a titan,i'm a kinda old guy,58.None of these things make me recoil sensitive to a moderate cartridge like the 10mm.If you're afraid of it the Glock 20c has a two slit compensated front.Glocks don't hurt when they are fired.They have a wide polymer grip that distributes recoil over a wide area of the hand.If you can fire a 9mm,you can fire a 10mm.It really isn't that ferocious.You can always bragg that you're tougher than an FBI agent if you can shoot it and not be scared off.The 40 S&W is the child of the 10mm.To appease the sensitivites of the FBI the 10mm case was shortened,less powder put in and presto the 40 short and weak.The G20 is the gun to have on you if you're life is in danger.Load it with Doubletap Ammo's 135gr Nosler hollowpoint load @ about 1600fps and no one is gonna laugh that off. In bear country,you can load the 200gr FMJ@ about 1275 fps.This is not the biggest,or the most expensive,or the prettiest,or the most expensive,but,like an AK47 it can be relied on to go bang evertime you need it to.I have two 10s,Glock 20c and Glock29.I recommend them highly.

I have carried a Glock 20 in the wilderness for 6 years. It is the most firepower in the smallest package. In the very wet forests of the Northwest the critters are very large and the streams very wide. I like the hitting power of the 10mm. After the third hour on the trail I like the size and lightweight features of the Glocks. I have sold my heavy .44's and don't miss lugging them around. I just picked up a Glock 29 and it is even smaller, and the mags from my G20 will work in the G29, an added bonus. Both of my Glocks were police trade in's and the price was 1/3 the price of new. I don't go for pretty just durability. Also, 3 times a year I shoot the pistol and know instinctly where my guns hit at 25 yards. Read More
I just purchased the Glock 20 SF and I was concerned about the recoil until I shot it. What is all the fuss about, it barely recoils. I love this gun, I wish I carried it when I was in law enforcement. Trust me, don't buy a 40, buy a 10mm G20 SF and get Double Tap ammo for it. You will love this gun. Everyone I have shown it to and shot it, loves it. Read More
Mine went KaBoom. My Glock was 3 months old and I was shooting new factory ammo. Glock was not help. Good Luck. Read More
