- I've been traditionally pretty anti-Glock, as I think there are usually better options on the market. But I decided to try out the Glock 20 gen4 as there weren't very many polymer-framed handguns out there. Of course as soon as I bought it, Sig released their X-Ten and Springfield their XD-M Elite, either of which I probably would have rather had. Oh well. The Glock 20 is definitely the handgun you want if you want to change out a bunch of parts and sort of make it your own. No optics mounting option though, which is a huge downside.
the reason for case bulge is Glock has a more loose tolerance for reliability like extraction, Glock is a combat gun made specifically for reliability thus loose tolerances so gun can function but reloaders dont like it because the case wears faster and even splits from factory barrel bulging the brass, but yes the after market barrel is for those who want to reload, i have a 40 cal barrel to, you can shoot 40 in your 10 mm but it wont chamber all the way, the extractor holds shell it the same possition as the 10 mm but has some free bore before it makes contact with the rifling making for some loads have accuracy issues or could have extractor issues eventually since extractor has to hold shell in place where as 10 mm bottoms out and less stress on extractor because of proper head space fit. the Glock 20 remains also still a little more reliable in all ammo then Sig, XD and smith and wesson 10 mm's. any hard cast loads Glock recomends a after market barrel since it has traditional rifling and not polygonal like the factory barrel, a few sending through is fine but it builds up and Glock recomends not shooting it but with a after market traditional rifling barrel. the nice thing about the Glock 20 is its bigger and heavier then the Glock 17 9 mm or Glock 22 40 cal wich means when you put a 40 cal replacement barrel in it it can be shot fast due to low recoil and even seem like your shooting a 9 mm when your shooting the 40 or federal 180 grain 10 mm with 10 mm barrel back in the Glock 20 is like 10 mm FBI load wich is basically wasted case capacity to make it like a 40 but federal kept that weak 10 mm should people not buy a 40 cal barrel and want a weaker 10 mm for fast shooting, the federal 180 grain hydra shok in 10 mm defense load is about the same as a 40 180 hydra shok also
Usually after running hardcast through my Glock 20 I give it a good cleaning for good measure. Glock on the other hand does not recommend running regular unjacketed lead rounds through their barrels, but hardcast bullets aren't the same as a regular lead bullets because they aren't made to expand like regular lead.
@@bdr32965 soft cast i never tried but hard cast does build up gunk on rifling as Glock said, also concearns of higher pressures being a polygon riffling, my thought is limited hard cast but as Glock said best to get a conventional rifled barrel like a double diamond, i chose a 40 cal barrel for my Glock 20 for hard cast lots of 40 offerings like underwood 200 grain 40, not as much power but very good performance for being a 40 cal, for the 10 mm if i do shoot hatd cast its usually a few rounds but i stick with Glock and that advice, long term maybe with out cleaning barrel may raise pressures to high possibly
Your comment on Glocks being set up for super weak 10mm ammo even weaker than 40 cal is bullshit. Learn what you’re talking about instead of spewing crap. I’m up here in Alaska the brown bear capital of the world. The Glock 20 is the absolute number one carry gun in this state. Most of which are box stock by the way. They handle the heavy loads just fine. The only after market part besides the sights that you would want is a barrel with regular rifling to shoot lead bullets.
Like I said in an earlier comment, I have ran 220 grain hardcast Buffalo Bore through my Glock 20 without any problems whatsoever and everything on my G20 is all stock parts.
The Glock fort is awesome and yes it is hard to find decent ammo most of it is crap
You didn't need to change the spring or guide rod, per Glock. And the barrel swap might be better for reloads, but it is tighter and potentially less reliable. When facing a threat, I'm far more interested reliability than reloading. Buffalo bore wrote a nice article about using hardcast in Glock stock barrels- they and Glock both seem to think it's ok. Your gun, of course, you can replace the barrel with a carrot if you want. But you should be aware of the drawbacks.
I’ll definitely check out that Buffalo Bore article, thanks!
My Gen 4 Glock 20 is fully stock, I can tell you for a fact that I have never had any problems with firing hot 10mm rounds through it. I have ran 220 grain Buffalo Bore hardcast rounds through it many times and not once have I had any issues using them.
The Glock20 is better than all of those guns, the Glock20 has about 30+ years on those other 10mm pistols as well.
Glock was designed specifically for the Austrian military, so by it being a military pistol it has looser tolerances for more reliable extractions.
The Glock20 was created in 1990 for the FBI with that same reliable combat chamber tolerance.
Glock20 specifically tells you not to fire reloads in there pistols, so it's not Glock, it's that you failed to do your research brother!
The pistol was made for war and to be reliable in the theater of war, it wasn't designed with the intention for reloaders, so you did the right thing getting an aftermarket barrel, if you're reloading.
Every Glock chamber is slightly oversized, it was engineered into their design.
Great demo on the barrels i was going to get one for one reason no idea what you demonstrated excellent
Great video
Good video brotherhood 👌
Anyone reading this…. Do not listen to this guy, he doesn’t know what he’s talking about… at all
Great job Sheldom. Love you on the TV shows 3:12 too.
Looking forward to the 10mm reloading vid
Very informative video. Thanks for posting. How heavy is the stock G20 recoil spring?
I like the way the m@p m2.0 10 m m looks The ergonomics looks a little better from the other ones
I never bad any cases split or gun blow up after shooting many hardcast bear loads from Buffalo Bore and Underwood.
Good to hear! The more I think about it, and the more I read comments, it probably has to do with the brass being resized once before. Could be that hot loads need to be in new brass in a factory Glock chamber to be safe. Thanks for watching!
The Sig Ten X has a issue feeding 230 bullets, there are videos out there on this issue. I do love the Sig P220 in 10mm.
That seems to be the case. The heaviest I’ve shot in either the Glock or Kimber is 200gr, so I can’t speak to how the 220s or 230s feed in them.
@@TheOutdoorGeneralist I know the Glock 20 can shoot the 230 grain, but I am not sure about the Kimber as well. I think the XD Elite can shoot the 230 grain.
First thing I did was install night sights on mine and that's all it shoot good and accurate
I use a Redding Buldge Buster die for 40 caliber because of the same issue.
I’m that guy who sold his Glock 20 for a Springfield Ronin in 10mm and haven’t looked back fully supported barrel G.I style guide rod and a few extras but hasn’t let me down and a couple members at my family Deer camp have taken a few deer with it themselves. It’s all about what you like.
MY GLOCK 20 10MM SIGHTS ARE AMAZING AND IF THERE WAS A CHANCE OF ME COMING ACROSS A PREDATOR I WANT SOMETHING THAT HAS BEEN TESTED AND PROVEN GLOCK ALL THE WAY
I shoot hotloads all the time out of my stock Glock 20 gen4 . I haven’t split a case yet. But you know what after your video I’m going to look into a aftermarket barrel!!
He said once fired, so he's saying the he's firing reloads, which means that the case has be resize to properly hold a bullet again and fit a chamber, but the brass of reloads especially for magnum cartridges is very stressed after being fired, so if you're reloading a magnum cartridge like the 10mm Auto you're playing Russian Roulette even .40S&W will kaboom, these are high pressure cartridges, use new brass, and you won't have to use an aftermarket barrel.
This is probably true. It is a higher pressure cartridge than a 9mm for example. But the point of reloading is to reuse the brass several times to save that cost. The aftermarket barrel pays for itself in about 500 rounds of brass that can be fired a second time, or 250pcs fired 3 times, etc, if I'm remembering my cost figures correctly.
10mm is a fair amount less powerful than the standard 41 magnum. 10mm is much more equivalent to a .357 magnum.
From my understanding a hot 10mm load is only slightly below the low end of a weaker .41 magnum load, but still between 20 - 30 percent more power than a heavier .357 magnum load. Still wouldn't want to test that theory by being on the receiving end of either one though.
@@bdr32965 I don't think that a 10mm is 20-30% more powerful than a stout .357 load. I just bought some Underwood 158 grain .357 mag that is humming along at 1500 fps and making upwards of 780 ft/lbs. That's as much or more than any 10mm I've seen. I haven't chronographed it, but Underwood is known for being close to their claimed velocity. That's up around modest .41 mag territory for power.
Glocks are made with looser tolerances for feeding and reliabilitu, just like AK's. I am not a fan of the Glock 20, it is decent but leaves much to be desired. The trigger sucks too, feels mushy no clean break.
Agreed, mushy trigger for sure. A lot different than other Glock triggers I've shot. My friend that carries a G19 daily commented on how weird it is.
Just wondering if your chickens have damaged hearing😊
They have to by now 😂
What weight spring did you put into it?
23#, IIRC
@@TheOutdoorGeneralist great video I am a new sub.
@@jimd1968 Thanks, glad to have you!
why would anybody want such a small gun the other reason I went with the Glock I like the Glock 40
they are ugly but they work thats why i bought one yes 1911s are nice looking but they are finicky they need work but glocks do not need much or do not any at all
Thousands of round " underwood ammo " out of my glock 20.... never had a problem or a blow up !!!!!! LOL
I guess having a spring weight to accommodate common/available ammo is a good thing but yeah all us 10mm owners want readily available and powerful ammo for less than $2/round
F u manufacturers
One of the major reasons I reload. Factory ammo prices are painful.
Curious, who informed the Creator of this video that the Glock 20 was designed for the super-weak ammunition? Definitely a false narrative. Please engage in detailed research prior to communicating any further on Glock, as well as any other topic. Without complete details, this is slander!
I suppose that came out a little strongly. That comment was based on my own observations of the factory ammo that I could find vs the experience I had with my own more spicy ammo. Suppose I should do a follow-up video when a better variety of ammo is available, though it would be slightly painful to ruin brass putting it though the factory barrel.
@@TheOutdoorGeneralist, as an owner of several Glock 20 Gen 4's, I have battled tested my firearms with "hot" to "light" loads without any difficulties, or modifications to each of the firearms. In addition, I normally shoot "hot" loads as the preferred choice of ammunition. Many of my colleagues that I deployed and served with overseas, utilize hand-loads as their preferred choice of ammunition for over 23 years with their Glock 20 Gen 4's without any difficulties. If read the manual, hand-loads, reloads, and remanufactured ammunition is highly discouraged for usage. Therefore, I implore you to conduct detailed research with Glock 20 Gen 3 & 4 owners nationwide that are willing to communicate with you prior to discharging your own opinion.
"Facts go long ways, and opinions not grounded in facts fade fast!"
My xdms are 100 percent reliable and shoot hot ammo my glock 20s fail to feed. Xdm better reliability. You can buy aftermarket barrel, mag springs, recoil springs, sights and have double the money as the xdm which is still more reliable. I've been tinkering with glock 20s for over 12 years never been able to get them 100% with full power loads. Bought a xdme shoots everything reliable no trouble at all. Still like glocks just not in 10mm.
Thanks for watching! I’ve got my eye on the compact XD-M Elite. Haven’t decided yet if my next 10mm will be that or the Sig X-Ten.
Might have a bad one? I have a 40 MOS, and a 20. Ive ran everything from Buffalo Bore, Underwood, G2 Research, Liberty Defense, and a ton of el' cheapo JHPs plinking. The only handgun ive ever had fail personally, and during training watched magazine bases fall out (best case) all thr way to not function period. That was my agency issued Smith & Wesson model 1076. Smith sent a gunsmith to our range with literally a van loaded with new 1076s to replace the units as they failed. This was while i was in the State Police academy, within months thr agency switched over to glock 35 tactical 40 cal as primary and a glock 27 (.40 cal) ankle gun.
This guy looks like bear food
They took our glarks!
