G20 Long Slide worth it?

I'm looking at getting a long-slide for my Glock 20 10mm to use as a dedicated hunting pistol to run with a red-dot sight and a suppressor. I'd still run the regular upper for everything outside of hunting such as self-defense and such.

Does anyone here have experience with the long-slide uppers for the G20? It seems like a great way to really maximize the 10mm's power, but I don't know if it's worth the effort.
 
I think for simply maximizing the performance of the round, you'd be fine to just go with an extended barrel and save a lot of money.

However, if you want a separate slide with the red dot dedicated for hunting use, then it would make sense to just get the long slide version as well.

I haven't used any of Lone Wolf's slides, but I have used quite a few of their barrels and have had nothing but excellent performance out of them. I think you'd be well served either way.
 
I don't think it is. When I was loading for the 10mm I had a LW Longslide for my then G20 SF. I had as much money in that slide that I could have just bought another Glock. It was heavy too, very heavy for a GLock. IMO, if you want more velocity it's cheaper to just buy a longer barrel and stick it in the G20. It may not look as good, but it's a lot less pricey.
 
How much more do you think you can get out of the long barrel with slide really ? Prob not enough to worry about. I'd send my slide to someone like Zebs and let them machine your slide for a red dot or whatever and if you need just but a longer barrel if you think the extra umph is worth the price. Not me though. I like the Glock 20 as is. Sights and all.

Normally I'd agree, but I need to get a threaded barrel to run with my suppressor. So I figure I may as well get a 6" barrel instead of a normal length one as I'll be using the threaded barrel for hunting.

However, that 6" barrel dangling out there with a can on it may look a little too goofy for me and that's why I'm looking at the Long-Slide option.
 
Save your money and just get an extended threaded barrel. The longslide may look cool but about the only advantage it offers is a longer sight plain with fixed sights. Since you plan on using a reddot there is no advantage.
 
That's a tough call. I agree it might look a little goofy to have a longer barrel with a can on it, with a stock slide.

If you have money to burn I'd say go for it, it would be a big long heavy Glock, but it would look cool and give you a bit more velocity.

But otherwise I'd recommend getting a new threaded barrel that is basically the stock length (minus the threads of course) then have the stock slide machined for a red dot. That way you have an all black Glock with suppressor and red dot... it would be practical for all of the above with no need to change out slides, and you can still take the suppressor off depending on your application, you'd just give up a little barrel length, and the "custom long slide" look. I really think this would be the way to go.

I'm going to get a lone wolf barrel for my Glock 21 so I can shoot 45 super, and I'm going to go a little longer than stock, just because I can. But if I were going to use a can with it I would not go longer, and I couldn't justify the cost of a whole new slide just for a little longer barrel

I've also avoided buying a mech tech carbine upper for any of my Glocks because I can't stand to have half a gun sitting around that needs to share lowers with another gun, I don't have any uppers in ar's that don't have their own dedicated lower either.... I just can't do it:o
 
ain't no death ray no matter how hard I pushed

IMNSHyetesteemedbymeatleastO&E a longer barrel in a 10mm Glock will not return sufficient velocity to be a worthwhile pursuit (in fact, without actual testing, one only guesses that a longer barrel will increase velocity).

For deer/smaller any modern 165--180g HP will suffice; for black bear/hogs suggest a 180--230g WFN choice.


I had Mr. Jarvis hard-fit one of his superb barrels in my M20. Jarvis or KKM.....
 
Sorry but I didn't see earlier it was for a silencer. I'd also just go with a longer barrel with same slide and gun. But we all have different opinions too.
My son just got a 17 gen 3 with a threaded barrel just basically for the threaded barrel to use on a gen 4. So same there. Different people have different opinions. Lol
And he has a Glock 45 idk the model but a full size with threaded barrel and a can also.
 
I went with a 9" barrel for use vs hog & deer...yes, it looks a bit odd,
and I have been bugging certain aftermarket suppliers to make a "Super Longslide"
for it so it'll look better...but it is strictly a looks issue, and not a performance one.

Chances are I'll have someone do a custom super longslide eventually...
just so it'll look nearly as cool as an AMT Javalina or Hardballer ;)

A number of years ago I built a 10mm "Practical/Tactical" with a new SF G20 frame, a LWD slide and a custom ordered KKM barrel. By the time I got everything together and working (including two visits to Robar) I had way too much invested and it was still ammo sensitive. It would shoot my hand loads but was picky about factory ammo. Between that lack of Glock-like reliability and the money I had tied up in it, I eventually sold it for a quite a loss.

Based on my experience I'd vote for just an extended barrel. YMMV.

I've been thinking about threading the end of the 9" and screwing a comp on that'll match up to the OEM slide...
best of both worlds that way, longslide look & a comp to handle some of the recoil/fireball...lol
 
I did some experimenting with 155gr Speer Golds loaded by Georgia Arms. I gained and average of 70fps when I from the factory G20 barrel to the 6" and that translated into about 1/2 deeper penetration into ballistic gel.
If it were me I would just go with a longer barrel instead of the slide and really only for the suppressor.
As I am sure you know stay with heavy slow bullets (under 1050 fps) for the suppressor to be completely effective.
 
I wish that i had the $600.00 or so to have a 9" slide/barrel arrangement. talk about a "deer stalker" of a pistol! With a fully-supported barrel and velocity increase (accompanied by enhanced brass life and sighting plane) it would make for the "ultimate 10".

In the vernacular of John Travolta in the motion picture "Broken Arrow":

"Ain't it cool"?

Actually, something has occurred that has me rethinking 10mm altogether...
had pretty much settled on getting a G40 Hunter model, but then saw a G30
that was set up for .460 Rowland, which is even closer to .44magnum
At that point started doing research on .460R, and am pretty darn impressed :)

Upsides;
.44 Magnum performance can be had in almost any .45acp package
Uses same mags as .45acp, as the ammo is the same length.
1911, XD, G21/30, and a bunch of other conversions are available
Recoil is manageable thru the comp & semi-auto platform
Blows BIGGER holes in everything than 10mm
MechTech CCU available :D

Downsides;
Loud, but not as loud as an AR pistol ;)
Requires a compensator or very specifically ported barrel,
either way...longer barrel than standard...
Ammo is Pricey, it is a Reloader-Only round as of now,
or if you are filthy rich...
When is the last time you saw a box of .460 Rowland at your LGS?
Might as well use a Glock or XD, as it'll pound a 1911 frame mercilessly...
requires regular recoil spring/buffer changes...
Rowlanator suggested...which is another $50...

Where all this has me headed is probably towards a LoneWolf G21 frame
with a MechTech CCU in .460R

But I still want a G40...only time will tell which way this one will end ;)
 
I own one of the IAI Javalina pistols. I love it and will never give it up. I also own a Model 20 and will eventually buy a 9" barrel with a fully supported chamber. This will make the 10mm flatter-shooting, harder-hitting and extremely accurate! Lord help me, I love the 10mm Auto pistol cartridge! It fills every catagory for the medium-to-high powered auto pistol cartridge without a hitch! :cool:

Putting it simply, It works! :D

From a conventionally rifled 9" barrel a Buffalo Bore 180 grain JHP leaves the muzzle at 1509 fps. this translates into 910.34 foot pounds of energy. This should prove ample for deer, or even Black Bear even at 100 yards from the muzzle.

It's "sufficient". ;)

There is a reason why the 6" aftermarket barrels like KKM are popular with G20 owners such as myself. With stout 10mm loads, you can hunt deer and smaller game. Otherwise, a Marlin Guide Gun in 44mag. But hey, is a Glock. Why not? Most have several anyway.
 
Don't think so

With the G40 on the market, building a long slide 10mm seems spending your money for the wrong product. The G40 is optic ready, has a slightly longer tube, match/hunt trigger....no option for a suppressor though. That is why there are ear plugs/muffs.
 
You can get a 6.5" barrel that is threaded for a supressor. Keep looking for the proper barrel, (KKM, Bar Sto, Lone Wolf, among others) and buy a suppressor for the purpose. Do your homework and buy the barrel that will suit both the projectiles and the barrel's purpose.

All the best.

This.

I have both the G20 and the G40. Both have been 100% reliable, and both are accurate.

But thanks to the longer sight radius and the lighter out-of-the-box trigger, the G40 has been very accurate with most factory loads (more so than my 20) and the few handloads I've had time to run thru it.

Understand that the handling characteristics of the 40 differ markedly from the 20, due to the weight of the longer slide and barrel, and the double recoil-spring assembly which reduces slide speed, as felt during recoil and recovery.

It's just something you have to feel to understand and appreciate. So if you can, try to find someone with a G40 who'll let you shoot some rounds thru it.

Bottom-line: you're better off just getting the G40 in the first place, if you want a long-slide Glock 10mm, rather than parting together one from a G20.

G40.
