Greetings. I've been lurking, researching hard about the 10mm and I've decided to buy a Glock, probably next week, probably a Glock 20. I've read about Glock 20s kabooming or having fail to feed issues with HOT heavy loads. I dont reload, will buy factory ammo. I DO NOT wish to upgrade the barrel and recoil spring. I've read here somewhere that so long as you stick to the 1200fps with a 180-200 grain bullet, problems are rare.
Based on my research, for woods carry(in the Southern Appalachians, where I'd need a round suitable for black bear, hog AND people) and possibly for deer hunting, I'm thinking either Federal JSP or Underwood Extreme Hunter. Heres where I ask for your experience, with either these two or something else. I want the best DO IT ALL round that wont jam or break a stock G20. I understand DO IT ALL means compromise. Thx
A Glock 20 Gen 3 or Gen 4 will serve you well. Factory ammo should shoot just fine from the platform for your intended use. I have a Gen 3 SF and have never had an issue with factory ammo or with handloads that were within velocity and powder charge specs from a published data source.
Welcome bigben,
The G20 is a fine weapon. As for woods ammo, you'll have to either find a happy medium, or pick one that will work best for your biggest concern, E.g. bear ammo would likely be Underwood's 220 hard cast, deer, Underwood's 180, or 200gr XTP, as for two legged predators, any of the above will work well

bigben55, welcome to the forum! The G-20 Gen 4 has a different recoil spring set up than previous generations. Myself I got the 20SF Gen 3 model and it has been a great pistol for 10mm from mild to wild that includes Underwood, Buffalo Bore, Fenix and Double Tap as well as my matching handloads. I do run a Wolf 22lbs non captive recoil rod & spring because it provides me with options if needed. I run conversion barrels for 40S&W, 9x25 Dillon and even a 9mm that needs a much reduces spring setup.
Although I have aftermarket barrels I carry most of the time with the factory barrel...
Thanks! I emailed Underwood, who assured me no modifications to a Glock 20 are needed for their ammo. He did say the 200 and 220 HC recoil the most and for some shooters, a 22lb recoil spring helps. But, limp writing is by far the #1 cause for failure to feed issues. I'm a big guy with big hands, have no problem one handing a .44mag Super Blackhawk and really dont consider myself recoil sensitive.
I do want a happy medium full power round. Anyone have experience with the Underwood Extreme Hunter 150gr? Seems like it could be one.
Are there any significant advantages going Gen 4 over Gen 3? I know the differences on paper, but does the gen 4 double recoil spring matter THAT much? I doubt it add backstreps to the handle; my gen 3 Glick 17 and 26 fit me just fine and have for over 10 years.
+1 on the Glock Gen 3 SF here.
Stay away from the hardcast with any generation of 10mm Glock (polygonal rifling tends to lead up with Hardcast). The Glock is an excellent choice for woods carry!
As others have said it'll handle the mild to wild stuff just fine. That Glocks won't handle the hot stuff business without kaboom in is complete hogwash! Defective ammo or bullet set back is far, far and away the #1 cause of kabooms! It can happen with any firearm particularly 10mm as its already a high pressure round.
Underwood Extreme Hunter or Defender will work great. Lots of good choices for your chosen application. The Underwood 200gr & 180XTP are great. The Federal Trophy Bonded you mention are good to go. Buffalo Bore 155 TAC-XP great option. Sig Sauer 180gr V-Crown works well. Any many others as well.
Many people like the heavier 22lbs to 24lds recoil spring on Gen 3; as they're very inexpensive and really help holding the slide back a fraction of a fraction of a second to get a little more consistent burn when shooting the hot stuff out of your Glock. Not imperative but helps to give consistent velocities to the projectile.
Welcome to the 10mm and wish you luck after you buy your first one. Your gonna enjoy it so much that it's likely just a matter of time till you end up with another, etc. Most of us here suffer with the affliction and very few of us have been able to limit ourself a to just one. Wait and see!😉
Wish you all the best and while we hope you never need it; your Glock 10mm will be more than capable of handling anything roaming around the Souther Appalacians. 2 or 4 legged!
Thanks for bringing that up Rojo, was thinking about that at work today. My G20 KKM Barrel works great for HC, but when using it for carry purposes with JHP's I always use the factory barrel. I really like the aftermarket barrels, but for overall reliability factory has been a constant winner
Ken
Depending on rules in your state. The SIG 180 fmj is a great factory round.

I have run two to three thousand rounds of Underwood through a Gen 3 SF and a Gen 4 Glock 20 (I would have to check my notes for an exact count).
If you are not planning on upgrading the RSA, then my recommendation would be to stick with a Gen 4. I had upgraded to the 22 pound on my Gen 3 which works great.
As far as ammo goes, the Federal runs great in the Glocks. The Underwood Extreme Defender / Penetrator / Hunter would give you more penetration if your main concern is large 4 legged predators. The Federal would be better for two legged variety. I have test fired the Underwood Extreme Defender and Penetrator in my Glocks and they both work fine. I have not test fired the Hunter round, so you might want to throw a box or two through the gun to confirm reliable function. though I know it gets expensive.
Good luck with your choice!

4949, have you shot the Underwood XTPs? They seem like another good compromise round. Would you go 180 gr or 200gr?
I have an early Gen4. Reliable with everything except 220g hardcasts from underwood. Those just slow the slide enough that they hang up.
In my experience, it runs fine in stock configuration. I messed with springs and barrels from the aftermarket, and reliability was more hit or miss. I just decided to stop spending money on something that wasn't broken and keep it box-stock. I sometimes carry in winter coat weather, especially in the field.
165g Gold dot underwood loads if I'm thinking two legged predators (or hand loaded approximates).
For the range, I play with the Tanfolio (EAA Withess) just because it feels so good in the hand, durable, accurate, and MUCH MUCH Prettier too.

The Underwood xtp's are great. I used them on a cow elk hunt. One shot it was a done deal.

Ben,
I have tried them both. For what you want them for, the 200 XTP's would be probably better. They feed fine out of the Glock 20.
Not to mention, it's a pretty badass load : )
I'll probably go with the 200gr XTP Underwood, thx all.
What do you find the cheapest but best range ammo? If I wanted to convert the G20 to .40S&W for range work, what all do you need to buy? Barrel, mags, recoil spring? Or what other calibers have you done conversions to? I have 2 Glock 9mms already for CCW and range work too.
My G-20 sports conversions for 40S&W, 9x25 Dillon and 9mm still trying to locate a 357Sig conversion...
My G-29 sports 40S&W, 357Sig and 9x25 Dillon conversions...
You would just need a conversion barrel to .40 cal. I have one for .357 Sig. Works perfectly..
My "range ammo" for my 10mms has always been my reloads. In the 3rd Gen Glocks 20SF and 29SF, that has meant Hornady 180 grain XTP or HAP at +/- 1200 FPS. In the S&W 1006 and 1026, castings have been the rule, both 175 Lee truncated-cone/conventional lube groove variant and the RCBS 200 grain truncated-cone design.
I have been a pretty active bullet caster since 1981. One of the larger discussion areas within the casting community has been "Polygonal-form bores and their safety with cast bullets". LOTS MORE heat than light gets generated in these discussions. What follows is my viewpoint to the present time.
A few years ago I ran 4 designs of cast bullets sized at both .452" and .454" through a couple Glock 21 pistols. Two provisos, up front--1) Glock 45 caliber bore forms are octagonal, vs. the hexagonal bore forms of their 9mm, 40 S&W, and 10mm barrels. 2) the 45 ACP is a VERY lead-friendly caliber--low op pressures, fairly slow rifling twists, very consistent bore dimensions over the years. 9mm is the polar opposite, 40 and 10 tend to have consistent dimensions but retain the fast twists and high op pressures of the 9mm. Dimensionally, the 9mm is all over the place. For purposes of bullet casting, the 9/40/10 should be treated as RIFLES.
The Glock 45s were a delight with castings of both sizings and all 4 designs. Zero leading, even after 800+ rounds without cleaning in one of the pistols. Nothing exotic about alloy or lube, either--92/6/2 metal and Alox/beeswax lube. Kinda pedestrian, that.
I am about to start extensive work with castings in our Glock 40 S&W and 10mm pistols. I will make haste very slowly, and I get even a hint of lead deposits anywhere in the bore I will suspend further work with the Glocks and give Bar-Sto Barrels some business. Slower twist rates and conventional rifling de-complicate cast bullet lifestyles MARKEDLY. And if you hear of any mushroom clouds rising east and south of Joshua Tree National Park over the next few months, you will know that my experiment came to a bad end.
Jury is still out, IOW.
Another project kind of on the back burner for now is load development in the 10mm (Glock 20SF) with Barnes copper bullets for hunting usage on deer. Lead and lead-core bullets went the way of 8-track tape decks in California as of 07-01-19. It is all unleaded here now in the hunting fields. I would love to hear back from anyone with real-world experience using these combinations. TIA!

Do a YouTube search for Razor Dobbs 10mm....
He has utilized Double Tap 155gr Barnes 10mm ammo to harvest:
Whitetail Deer - several of them
Wild hogs - several of them
Bull Nilgai - huge Asian Antelope
Bull Elk
He raves about Double Taps loading of the Barnes 155gr
(course a sponsor no doubt) however the results are easy to see.
