Glock 20 recommendations - 10mm Ammo

I like the 200 grn. JHP for my just about everything load here in CA. This is one I have had good luck with shooting hogs, others have stated they did not:

I would think that the Underwood 180's would be a good choice as well. All ammo should be tested for function first.

I have had my 20 for about 15 years and it is a great gun, I hope you end up liking yours as well.

Hickok45 did a video with the heavier bullets in a stock barrel and had issues with tumbling. I can't look for it right now, and I'm only working from memory, but it's something to consider.

I believe the bullets that keyholed were something like 230gr Underwood or Buffalo Bore. I think they supposedly work in aftermarket barrels with faster twists though.

The brass is of no use after you fire it. Box it up and sent it too me and ill dispose of it properly!

Did you go for 10mm for the power? just curious. It seems like they are popular or getting more so for animal defense. Between buying a gun and the cost of yet another caliber, I just can't justify getting one. Where I live the worst thing you MAY run across in the woods is a black bear. I rely on my Glock 21 (45), my average or hopefully better skills, and the knowledge that I have 13 chances to get it right!

Just try not to make it mad twelve times....

I can't explain it, but the Glock 20 feels great in my hands and I shoot it well... something I cannot say for the other Glocks I've shot. It's on my bucket list.

Not that any handgun is a great choice for critter defense, but the 10mm offers a whole lot more penetration than .45 ACP. Smaller diameter bullet with higher sectional density and a whole lot more oomph behind it. In my informal testing, a 10mm 200 gr. TMJ @ 1,280 FPS actually out-penetrated a 325 gr. Speer JHP @ 1,510 FPS from my 6" .50 AE Desert Eagle

For a mid range load at a good price these are hard to beat if you don't handload. Even if you do this is a good price.

These are out of stock at the present time, but for carry I use these.

And when in bear country these.

I picked one up a couple of months ago and love it. It didn't seem to like 220 Grain hard cast ammunition. Some of the reviews I saw on Underwood's site mentioned the same thing. I'm going to give 200 grain ammo a try.

Underwood sells a 200gr XTP I carry. That bullet holds up at 10mm speeds.

I also always have a magazine with Double Tap 215gr WFNGC on me since I'm close to forests. Both my Glock and my 10mm 1911 handle it well. DT stopped offering the 215gr bullet, but their 200gr WFNGC should leave the barrel of your G20 at least at 1200 ft/s.

I have a couple boxes of Underwood's 220gr hard cast. The bullets are probably at the top end of weight. They averaged 1088 ft/s from my Glock 29. I didn't see the stability issues 'hickok45' observed, but I go with lighter 200gr bullets.

First thing I would do with a 10mm or any glock for that matter is get some good adjustable sights. I love the 10mm but because of cost and recoil I really take more time to aim than slapping on the trigger like my competition 9mms.

I'm partial to the speer 10mm 180gr gold dot myself but I tend to like gold dots in generally for defensive ammo as I can always find it. Never saw the point of the various flavor of the month brands that are hard to come by. I like to shoot and shoot a lot so I need to buy in bulk and find it throughout the year.

I would not want to face an angry bear w/ a 45. Honestly I don't want to face one w/ out a rifle or shotgun full of slugs. But I feel a lot safer carrying a 10mm in this situation. It's exactly why I bought a G20SF.

I can't help the OP because I cast my own bullets and reload. I bought one box of factory ammo so I had brass until my order from Starline came in. The price of factory ammo would mean little practice for me

I like the underwood 200 XTP for woods and all around carry. The 180 XTPs (used 1 box) seemed good too. Velocity was as expected for both loads in my G20.

I also load up 180 gold dots to about 1275 for 2 legged goblins.

Have not tried the hard cast stuff.

I would be leery of Doubletaps stuff... there is a lot floating around about actual vs advertised velocity. Have not used it myself though fwiw.

Recoil on any of the loads is tolerable in the G20 and I don't really find it much of a hinderance to my shooting. I am a bit slower than when I shoot 9mm, but defensive 45 ACP out of a G21 is comparable really. If you have shooting the hot stuff really often consider getting a slightly heavier recoil spring in there to keep the gun from beating itself up. I left the stocker in mine since it does not get shot with the hot hot stuff much.

My 10mm experience is shortlived, but I will give it another go because I really like the round. I loaded 180gr berry's plated flat points over bullseye. I don't recall the charge, but it was about 1/3 of the way from bottom to top on the ladder tests for a similar jacketed bullet. I fired it 4 times on a 200ish pound whitetail buck at 7 to 12 yards (as he ran) 3 were on the shoulder, 1 was slightly back from the shoulder. One round had broken a single leg and even with a bone-strike on near side every bullet exited on the opposite side. So 3 went through both shoulders, and 1 went through the ribs. The bullets must have expanded well because the wound channels were huge on the exit side. I have large hands and I could easily stick my thumb in the holes. The shoulders were not salvageable from the damage. Luckily my shot further back was lower and did not destroy tenderloin. I have full confidence in the round that I had loaded for anything up to black bear. For larger or more dangerous game I would step the load up to semi jacketed flat points and run them full-tilt if accuracy held together.

Since the OP isn't handloading yet and given the limited factory options, Double Tap is an option. Based on my experience, the Underwood 220gr hard cast bullets are a bit too "fat" for reliable feeding.

As I wrote above, DT's 200gr WFNGC should leave the 5.5" barrel of the OP's G20 at least at 1200 ft/s.

DT used to make ammo that met the specs on the box. I have a stash from ten years ago. 'Intercooler' and I both chronographed a sampling of those original loads. DT should have stayed with that.

But, now one must assume the DT label has exaggerated values. But a 200gr hard cast bullet moving at 1200 ft/s is decent performance against bear or deer from a semi-auto handgun.

Dragon- I'm not an expert on bears, but I spent some time hunting them (black bears) in Maine last Sep. with local guides who are experts on them. They mostly carried 45's for wounded bears they track. One of the guides (a former state game warden) put down a wounded bear (wounded by a 308) trying to go up a tree with a 9mm. A rusty Star 9mm. No kidding. I had noticed the pistol in his holster earlier and I just thought it was a 1911. I didn't realize it was a 9 until the bullet dropped out of the carcass when we were cleaning it. I asked him why he didn't use a bigger pistol, and he just said it was fine as long as you can hit where you aim. Another guide carried a riot gun full of OO, only because he said he can't hit s--- with a handgun.

10mm will get you started hand loading lol. THEN it is an awesome caliber. It can do everything from gallery loads, to 9mm power to full house 10mm.

I like it for the versatility. Not to mention the fact that G20 Frame can easily be made to fire just about any caliber you want. mmmm 9x25 Dillon lol

For plinking I've been messing around with some of that sig ammo because it's really inexpensive and it's kind of in the middle of the road as far as power goes for a plinking round. A lot of the other ammo you come across is barely hotter than a .40S&W if at all. The sig isn't loaded hot or anything but it's a bit hotter than some. I'm going to go grab a box or 2 of their JHPs later on today and see how those do too. Might be a decent choice to just keep around in bulk if you don't reload and it's not $30/20 like some of the others.

For reloading, the XTP bullets are a good choice since you can push them as fast as you are comfortable in 10mm and they will still perform as designed. They are also not the most expensive JHP bullet and you can get them at box stores which is nice.

Underwood, buffalo bore, and doubletap seem to be the top 3 (in no particular order) for some 10mm rounds that have some gusto out of the box. For hunting I'm thinking about a 180 grain xtp over some longshot and with a 6" barrel could probably push it around 1300fps without going too crazy. That should do the trick.
