I wish I knew how to borrow and post a story from Glock Talk.

There is an article about a guy in Alaska stopping a grizzly charge with a Glock 20 and HSM ammo.

U.S.A. –-(Ammoland.com)- On 19 September 2018, Jimmy Cox used his Glock model 20 10mm to stop the charging grizzly bear pictured, at 10 feet. The incident leading to the dramatic events occurred the previous evening.

On the evening of 18 September 2018, Anthony Reyna was happy and excited. He and his friend, Gary, were hunting moose on Joint Base Elmendorf-Richardson north of and sharing a boundary with Anchorage, Alaska. Tony had drawn a moose tag for a bow hunt. He was using a 60 lb PSE ThunderBolt compound bow. He has owned the bow since he was a teenager. Tony and Gary set up and started moose calling about 6 p.m. After 40 minutes, they heard a bull moving in. They saw his antlers at 30 yards. Suddenly, a second bull appeared at 15 yards! It was not as big, but Tony was hunting for meat.

Tony was able to take a shot as the bull moved 20 yards out. The bull turned at the last moment; the arrow glanced off a rib. It did not spook the bull, but the bull moved off 200 yards. Tony stalked it to 24 yards and put an arrow through both lungs. This time the bull ran. As they tracked the bull, the blood trail ran out with the daylight. It wasn't safe to search in the dark. They decided to come back the next morning.
At 08:30 the next morning, Tony was back with his friends Jimmy Cox and Ron Sheldon. It was cool, cloudy, and calm. They found the end of the blood trail. Jimmy Cox had the lead with a Glock 20 10mm in a Blackhawk Serpa holster on his right hip. Jimmy is right-handed. The three friends are experienced combat veterans. They decided to do a grid search in the direction the blood trail was leading. Ron went up a hill to help guide the search from an elevated perspective.

The area is heavily wooded in black spruce and birch, some aspen, with plenty of undergrowth and downed trees.

Tony and Jimmy head out. They hear crows about 50 yards away. Jimmy says: “That's where your moose is.”

As they approached the area where they heard the crows, the birds kick up. Less than a second later, they hear the roar, directly ahead. From 10 yards away, a large grizzly is charging them full out.

Jimmy is in the lead, about five feet ahead of Tony. He has time for a startled “F*ck Bear!” as he draws the Glock from the Serpa. He has trained and practiced. The draw is smooth and fast from a retention holster. As the bear bounds over the downed spruce, Jimmy double taps, two shots, one to the chest, one to the head. The bear crashes down, 10 feet from Jimmy, dead right there (DRT). It is over in a couple of seconds.

The bear is a big grizzly bear. The friends call Fish and Game on base to report the self-defense killing. Mark, with Fish and Game, shows up. He has no issues with the shooting. He estimates the bear at 800-850 lbs. It squares at 7 1/2 feet.
They are instructed to go to Anchorage the next day to fill out the required paperwork, the Defense of Life and Property (DLP) report. They were already busy with the hard work of skinning the bear and dressing out the moose. The moose had been buried by the bear and had its ear and genitals ripped off.

The meat was judged salvageable. Fortunately, a co-worker was able to get his truck within 100 yards of the scene, minimizing pack-out time. Tony was able to get back home, get the meat through initial processing and stored by 9:30 p.m. It had been a long 30 hours.

Jimmy's Glock was loaded with 200 grain HSN bear loads. The first shot took the bear in the chest. It penetrated the right lung, through the chest cavity, and broke the spine. As the bear dropped, the second round caught it in the head. Neither round exited the bears body. The friends could not follow the second round wound channel, because the head, skin, and paws had to be turned in. Because the bear dropped nearly instantaneously, Tony believes the second bullet hit the brain or top of the spinal colum.

Another poster, LJ Miller, on facebook, suggested it was the same bear he had problems with one year before, in the same area, September of 2017. He and his partner went to some trouble to avoid shooting the grizzly, which harassed them while they were packing out a quartered moose. It is fortunate Jimmy was there, was well practiced with his Glock, and in the lead. It could easily have been a tragedy.

This use of a pistol to defend against bear attack was not reported in the news. Without diligent searching, no one but the participants would know about it. If you know of a defensive pistol use against bears, please contact us. We include every use where a pistol can be reasonably documented as being fired in defense against a bear, in our database.

that is the eternal dilemma, a compact LW 9mm with 12 or so +P 147 grain hard cast bullets, or the much larger frame size 10mm, however after watching the 10 shoot through all of the gelatin I am leaning to the G29 with 220 grain hard cast. OTOH even a glock 30 loaded with the Buffalo bore 230 grain hard cast 45ACP ammo at 925 FPS would probably be interesting.

Is the 20SF a smaller frame like the 21SF?

It's kind of skinnier.

For those interested I have read a lot about 220 grain hard cast bullets not shooting well out of G20s. I don't have personal knowledge; but, I have read it enough such that I have been carrying 200 grain hard cast and they shoot great in my G20 and G29, even with the stock 17 lb spring if I forget to change it out. From what I have read it is usually an accuracy problem.

I've read that years ago, but it was always in reference to a particular manufacturer's ammo (Double Tap). Those issues all seemed to be caused by undersized bullets and weren't really anything to do with the weight; at that time some people were reporting pulled bullet diameters as small as.397-.398", when they should have been .401"-.402". That's definitely enough undersized to cause accuracy problems. That was 10-12 years ago though; I have no idea if Double Tap has fixed that by now, but would guess they probably have.

I've cast and loaded several different 220gr bullets over the years, even one design I made up myself, and never had accuracy issues with any of them in Glocks or other pistols.

That guy that shot that bear would have felt more confident and more well armed if he would have had a 9MM. Maybe a Kimber Micro Nine with 147 grain +P hardcast carried in Calvary fashion with the butt forward

From what I have read ,the grip frame size of a Gen 4 G20 without one of the other backstraps installed is smaller than the Gen 3 20, with some even claiming that it is a wee bit smaller than the Gen 3 SF..

How about the recoil/rate of fire thing compared with the 9 mil wimposaursus?

No, the 20SF and 21SF frames are exactly the same part. There is no difference between them other than the top ends (slide/barrel/etc) and the magazines.
