How 'bout turning your G20 into an 18 round .38 Super? Lone Wolf makes a .38 Super barrel for G20/40 pistols. Rumor has it the standard 10mm magazines work just fine.

Why?

Just for fun...not everything has to have a practical "mission".

RGK (BOB) will probably have to have a G20 now that it can be a .38 Super. I'm pretty sure the gun industry isn't allowed to make anything in .38 Super without clearing it through Bob first.

Probably more practical from a cost standpoint to convert to 40, assuming a person shoots and keeps 40 on hand for other guns. There is also a 9mm barrel made (but it doesn't show up in the regular catalog) but I have heard mixed reviews about reliability using 9mm ammo in 10mm mags. If I want to shoot 9, I just take a 9 to the range.

Uh hello people, no one said anything about practical. If you want practical just buy a Glock 19...like everyone else on the planet. But some want to do something different just to be different.

well, it's tempting to me. I could never rationalize enough buying a 38super already having .357sig. But i do have a g20, and i could see doing that to play with for sure.

Thanks. I've got quite a bit of 38 Super ammo laying around and currently no gun to fire it in.

The fine print says to use a 13lb. recoil spring and that #3 magazine followers won't work.

The 38 Super is a hard hitting round and IME recoils less than the 10.

Here's a good article regarding shooting 40 ammo through a regular G20,

Does anyone make a 9x25 barrel for a G20?

Or you can get a 9x25 Dillon and have even a hotter 9MM. Just saying.
Cheers NC

I have been doing this for some time.

I like the .38Super quite a bit. Never found the 10 even at Norma original loads to be bad in the G20 (yes, I need another one). If 15 of 10 can't get it done, I am hard pressed to see how 18 of .38Super would.

Though, I may still have to get the barrel after acquiring another G20.

Hmmm... A long slide Super....

Yep; works well.

If you shoot the right ammo, the 10 can become uncomfortable in that platform. I currently have probably six mags loaded with Privi Partizan 180 grain JHP. It exhibits pretty harsh recoil.

I never found the original Norma 200 grain loads to be that obnoxious. Stiff and snappy, yes, but not obnoxious at all. I much preferred them over 180 .357s or even stout 158 .357s.

that 200gr norma load is not bad i have fired in a normal length g20 barrel, a six inch, and in a ruger blackhawk with a seven inch.

So I should be able to fire 10 mm in my g22, right?

Actually been thinking to sell my g22, knowing that I can shoot 40s in my g20 might speed that thought along.

I still have yet to see any 38 super ammo in my locals, I would go with the 357 Sig.

I find that surprising, considering PPU 10mm ammo virtually replicates .40S&W performance. It is one of the few true "10mm lite" loads still available.

If I ever got bored with the flexibility of a 10mm, I'd buy a 9x25 Dillon barrel and keep grinning.

I don't know. I don't know what the ballistics are on it. I got it when I was low on 10mm ammo and that's what was available in fairly inexpensive offerings...ie 50 rds as opposed to the 20 rd. self-defense packs that are exceedingly high-dollar. I've shot a fairly wide variety of 10mm ammo including the original Norma stuff back in the 90's. This was the hardest kicking 10mm ammo I've shot. At least, that was my perception.

..just when I start thinking again of a Glock 40 for a car gun you have to do this to me...now I have no choice.

Thank you VERY VERY MUCH...Bob

I'm still surprised they didn't check with you first...big breach of etiquette on their part.

Please let us know if this get the Bob stamp of approval. The G20 is looking even more interesting these days. 10mm/40 and now .38 Super...how fun!!

I've had bad luck with Lone Wolf barrel's accuracy. The next barrel going in my G20 will be fit at Bar-Sto.

Sent an email to my dealer today about pricing on a Glock 40...I've seen them for under $700 and if he can do as good will probably order one...and then some barrels...

Now...do I go the TruGlo TFX or a set of adjustables...

A lot of guys have good luck with Storm Lake barrels.

I've tried Storm Lake too. No real problems, but no noticeable increase in accuracy. The only reason I'd go with a different barrel is to get full chamber support...get rid of that little Glock "smilie" that appears on the brass when I shoot 'warm' loads...and an increase in accuracy. I've used a Kart barrel in a 1911 platform before and was very impressed. Bar-Sto is on par with Kart.

I beg to differ. So does Les Baer. Look down the bore of each and compare and the difference is amazing.

yea, just look down the barrel and you can tell if it's a good one, LOL...

Storm Lake is bottom of the barrel in my experience. Sometimes you might get a good one, but it's pretty hit and miss. My complaints are with the bore and chamber, rough bores and non-concentric chamber/throat seem pretty common.

Well Geek pushed me over the edge...ordered the 40 today. Once it gets here then I'll be getting some dies and reloading supplies...

Have wanted a 10mm for a long time and almost went Para Hunter LE and may end up with one one day anyway...

I have had a early glock 23 with a barsto 357sig barrel. no issues. it has shot more of those than 40.
I like the kkm barrels too and have bought quite a few of them.
I did have the glow in the dark sights put on the 20, i never figured it for a target gun per se.
I do know you can put the top of a 21 on a 20, and vice versa.
there are multiple options with glocks.
I haven't really warmed up to the six inch barrel on the 20 yet tho.
10 is an interesting caliber, like in a blackhawk with a long barrel. They kind of smoke.
and i haven't had the urge to put a 40 barrel on the glock 20.

I just knew you'd have to have one once the Super barrels were available.

Congrats...........looking forward to the range report.

Thanks for the link. I've had a G20 itch for quite a while, and feel one for the G40 starting to grow now. I've got a fair stash of .40S&W ammo, so this approach is appealing.

An aftermarket .10mm barrel with a tighter, fully supported chamber should also make .40S&W reloads safe(r), assuming brass is well inspected and culled...........thinking only one or two reloads probably.

Well, I had two Glock 20s. I bought a Lone Wolf slide and sent it to Bar-Sto and had a barrel fit to it. It's a lot more accurate than any of the other Lone Wolf and Storm Lake 6" offerings. I have three 6" 10mm barrels. The accuracy of those barrels paired with the Lone Wolf slide was to put it mildly, discouraging. I had already talked to one of Bar-Sto's gun smiths about fitting a custom Bar-Sto barrel to my Lone Wolf slide. They said no problem. Took about 4 months, but the final product was worth the wait. I had to shoot it in. It took a minimum of 500 rounds through it to get it to function properly. I could see where the slide and the barrel were rubbing a little more after each session. At 500 rounds it finally recoiled, ejected the spent brass, stripped one off of the magazine and went all the way into battery. I had been having to push the back of the slide to get it all the way forward and fully in battery. I have a little over 1100 rounds through it and if functions without a hiccup now, and hitting inside the scoring rings on a B27 target at 100 yards has become boring. Don't reckon I would try to shoot a game animal at 100 yards with my Glock, but I bet I could hit hog or a white tail.

A drop in .357 Sig barrel for the Gock Model 20 would be more practical.

Ammo is probably cheaper and more readily available. And it is a better round then the 38 Super, IMO. For whatever it's worth. Flame on

What he said.

I still want to get a 357 Sig barrel, either for my 20 or 35.

I bought a 9 mm conversion barrel from GTs., (for my 27) the Alpha model. I asked them if they had the 100$ model, they claimed those models where not made anymore. The alpha cost a little more but they are really nice.

Try KKM. Had lone wolf to begin with got rid of it, have been using KKM ever since. Have one in my 20, and one in my 22. Both function flawless and exceptional accuracy.

The proper platform for a .38 Super is a nickel 1911.

Just buy a damned Tanfoglio Witness if you want a high-cap Super.....

If you're going to get a super, get an old Colt with a Swartz safety.
Then rent an office with a hat rack and a frosted glass window on the door...
Otherwise, stick with a glock 19.

"Item Not Found" is what came up on the link.

I have a 20, and currently am running a Lone Wolf .40 S&W barrel in it. I would be interested in making this conversion to .38 Super. Sounds cool.

Not to mention 18 rounds in the mag.

Super is an OK cartridge. might also work in your 38/357 revolver.

We differ.

Ended up getting a .357 SIG barrel for my G40... I have more than enough "proper" Supers without having another conversion... That and I really didn't want to mess with magazine tuning that one needs to do with the .38 Super barrel....

Count me down for another that's not impressed with Bar-Sto Glock barrels. The KKM barrels we shot in comparison were more accurate, and worked right out of the box. The "fitting" on the Bar-Sto barrel was a real hack job too; the bottom lug was apparently hand stoned without even using a jig, obvious from the different angles and rounded edges. That was not the mark of a real craftsman, more what I'd expect from a backyard mechanic.

And 400 rounds to get the dumb thing to cycle is retarded. Bar-Sto could do a lot better than that if they really were on top of it, without sacrificing any accuracy. Depends on your expectations I guess, apparently some people have been convinced that high prices, long lead times, and excessive tight fits are signs of quality.

When I took delivery of my Bar-Sto barrel there was no obvious places on the new fitted barrel where I could point out hand-stoning, sanding or machining. It had to be shot in and it is plenty accurate now. I had a Lone Wolf barrel and later a Storm lake barrel...both 6" of course. My turkey shotgun shot a tighter pattern than those two barrels did at 30 yards. I've had a drop-in Bar-Sto barrel in another Glock 20 that was much more accurate than any of the other after market barrels I tried or the OEM barrel. I did not try Kart then either. I had a Para Ordnance P-15 that I had customized around 1986 with a fitted Kart barrel. I carried it on duty for a year. The malfunctions got to me. I lost confidence in the pistol. I can clear malfunctions in my sleep having done the same motions over and over, thousands of times. Of course, the round was the ubiquitous 45 ACP. It was wonderfully accurate out to 50 yards. But, unless someone was shooting at me, I really wasn't justified in shooting at someone 50 yards away. Absent them holding a firearm there is not an imminent threat of serious bodily injury or death. I didn't need a firearm with such tight tolerances, and critical fit of the slide to the frame, and the barrel to the slide causing malfunctions. I sold it for a fair price and bought my first Glock; a Glock 20 Gen 2.5. That was the first of 6 Glock pistols I have purchased. The Glock 40, rested on a sandbag, puts the bullets into a group roughly half the size of my old duty pistol, the Glock 20 Gen 2.5. Frankly, I'm encouraged by the fact that I had to shoot it in. I know it's a glove to hand fit, and it's also reliable and accurate. I can't see a Kart barrel making that much more difference than a Bar-Sto barrel. Certainly not enough difference for you to be essentially calling Bar-Sto barrels junk, and the gunsmiths that fit them rank amateurs.

If you wish to get into a monkey poo-slinging fight, I'm your guy. The prices were not exorbitant nor was the wait time. They quoted me 4 months. They were done in 3. Now, long lead times is like plunking down a deposit on a Hamilton Bowen handgun. Do you think he's just lazy? Or is it because when shooters find a superior mouse trap they'll line up and wait ridiculous amounts of time to get their new and improved mouse trap.

I have a Defiance Deviant Long Tactical action on order and paid for. I paid them in September. The rep told me actions were a 10-month wait. Too long? Not when my gunsmith recommended Defiance actions for my next build.
