Loving the red dots!

 
Still the Glock barrels don’t have the case support !
The real reason to upgrade barrels. The Glock barrels could always shoot Hardcast coated or Gas Check but Soft lead bullets not recommended in any Glock .

My trail pistol for Alaska is a G20 with the standard length barrel 4.6”. I prefer it over the excellent G40 and 6”. The G40 with 200gr Underwood you should break the 700 FPE level in performance.
My gen 5 40 s&w is fully supported..... I would imagine the 10mm are as well.
 
Factory is not 20 pound !
It’s 18 pound !
I use the NDZ 22 pound spring and rod in my G20.
Underwood Ammo works great in it.
I handload but my loads are not quite as hot but just under Underwood Vel levels.
I went ahead and installed a KKM 4.6” barrel also on my G20 for a tad better case support.
20 # is what Rock Island Armory lists as standard for their single-stack 10mm's. I think it's a bit stiff, but it might be exactly the weight for "brown bear" loads if not the 22#. I'd consider it strongly if I were going to push the cartridge and platform. A busted handgun, whether it hurts you in its failing or not, is not a good defense against those giants! A friend of mine shot one 15 times with a .300 WinMag (he'd accidentally gotten into the bear's path back to its den), and the taxidermist said that 11 of those shots should have dropped the bear in its tracks. Something to think about when choosing a bear gun, they're a "whole new deal" when they get riled up, which is what happened to him as his guide saw trouble heading his way but missed his shot with a .375 H&H.. My friend was an experienced Alaska hunter, but that day he shat his pants and it was only two years later that he could talk about it.

It's something that I'd think hard about if I was going into country where there's a good chance of running into an aggressive brownie. I like 10mm, I have three of them, one of which I often CCW, but I'd far rather have a .454 Casuul, .460 S&W, .500 S&W or one of the big Automags if I couldn't carry a proper rifle in that kind of country. I've stood beside a mounted roughly 8.5' brownie, and I've never felt so small. Now imagine it angry and charging you!

If a 10mm is all you can carry then so be it, I'd dig on the Internet to find loads from reputable powder makers - many have most if not all of their loads online for free. The only reason I can see for buying a reloading book is not finding what you want online, or just wanting the comfort of the written word. The powder companies will still make a profit on your powder purchases.

Ordered some of those 220 gr to try in my 10. Already with KKM barrel and 24# spring. I carry my 10 when working here in the hills of NC for black bears. Likely going to try 3N38 or N-350 in it
 
Man, I wish I had your hand strength. I'm in my 70's and have a fairly aggressive form of arthritis, I don't think I could rack a 1911 with a 24# recoil spring - I have trouble with my .45's and my stock RIA 10mm is a bitch and a half to rack. I wish it was cut for a red dot, mostly because they give you great leverage ( that's why the red dot is staying on my XD/M Compact in 10mm - I don't know if I can rack the slide without it.)

Hey, we get older and we get weaker, and all kinds of new maladies beset us. The smart fellow is the one who realizes and accepts that, and makes the appropriate allowances for it, not the dummy that thumps his chest and says "I'm as fit as a fiddle, cough, cough".

Play to your strengths, not your weaknesses. I'm currently shopping for an EDC pistol that's of adequate caliberbut easier to rack than my usual XD/M Compact in either 9mm or 10mm, I have both. I shoot the 10mm better, but it's hard to manipulate if I have a failure. I'm looking for something easier that either.
 
If I'm hunting AK or Africa where I might be the game I take ONLY my FA .475 Linebaugh revolver. I stopped a charging blk bear at 6 feet with it, a Cape buff at 35 yards, and a 5000# rhino. Works quite well. Reasonably light to carry and extremely effective.

I much rather have my 454 but sometimes Im working and that super redhawk revolver is in the way. I also dont run into many rhinos in NC. I've had several run ins with black bears, some as close as 6' in the dark. Had they wanted my ass they would have owned me. Ive carried ever since
 
I believe the G20 factory spring is 18 pounds .
I quickly switched barrels to KKM and a spring to 22 pounds and got rid of the plastic OEM spring and Rod .
Ok! By your recommendation, I ordered an NDZ 22# spring with rod and a KKM stainless barrel for my new Glock 40. A friend came thru with a half pound of Blue Dot! Woohoo!
I’ll have a new hog gun!

I was looking at the pic and thier site. I saw a bullet with 15 BHN but your box looks like it says 22 BHN. Are you using gas checks? I’m lean on hardcast knowledge.
Thanks in advance.

My new KKM barrel arrived, I picked up a couple pounds of A#9 and 200 Hornady 180 XTP?. I just looked at Xtreme’s recommended velocities for their plated bullets and “not to exceed” number is 1500 FPS.
My plan is to load the plated with book loads and the factory G40 spring to get a feel for the gun. Then I’ll install the 22 pound spring and work up some.

I loaded Montana Bullet Works 200gr hardcast for a trip to Idaho back in the summer. Ran about 150 of them through my stock G40 without a hiccup. Pushed them 1140 fps IIRC with Accurate #9.

Good folks to deal with too.
