Here's one you won't be able to pick up at your local Wal-mart gun counter....how about a G20/21 Longslide with interchangeable 10mm and .45 ACP barrels?

There are several of us over at the 10 Ring who have put these beasts together. They are built on a standard G20 or 21 frame with a custom long slide from Lone Wolf or Bar-Sto and a barrel from either Bar-Sto or KKM. They may very well be the perfect platform for the 10mm. Do you want controlable firepower? How about 15 rounds of 200gr 10mms at 1,350fps! :cool: G20L and Double tap ammo...it just doesn't get any better than this! ;f

I read A thread over in the 10 Ring about these guns you all have been putting together. Well worth reading thats for sure.

I have to admit it, that is one gun I would love to own. I just cannot afford the huge price for that new upper.

Yeah, they aren't cheap. But, you can look at it this way.... If you buy the frame as a unit from Glockmeister, the slide from Lone Wolf and the two barrels from KKM, you can look at it as TWO custom pistols for that price. Then it doesn't hurt QUITE so bad.... You can look at it another way as well: If you were to have a custom gunsmith build you a longslide 1911 in 10mm from quality Caspian and Bar-Sto components, you would have three times as much money invested as we do in one of these G20Ls and it would hold half as much ammo. It's all a matter of perspective. (At least that is the argument I have been using with my wife...) ;f

I already have a G20. Looks like I need to investigate enhancing my Baby :cool:

I just ruined my keyboard with a puddle of drool. Thanks a lot.

some day my G21 will look like that.

But there are SOOO many guns I want to buy right now. Quit tempting me.

I've been looking at this project for a while.

I've got the cash to make it happen,but.... is it worth $600 to make the slide a little longer? I have the six inch barrels already. Is there a noticeable difference in accuracy or is this one of those "gotta have something different"deals?

Not that there's anything wrong with that. I've paid more for sillier things.

The G20 Longslide's biggest advantage comes from weight and slide mass. The difference in felt recoil between the standard G20 and the Longslide must be experienced to be believed. The G20L has no lightening cuts on top of the slide, so all of that extra mass slows the recoil impulse and slide speed down considerably. With the stock recoil spring, it is sometimes "over sprung" with light 10mm loads. My G20L doesn't like the PMC 200gr loads because they don't generate enough energy to reliably cycle the slide. The G20L handles heavy 10mm loads better than any 10mm I have shot or owned. It's almost like the G20L and Double Tap ammo were made for each other.... On top of all that, you have the advantage of a longer sight plane and a Bo-Mar adjustable rear sight. The only thing the G20L doesn't do well is carry comfortably in a Milt Sparks VM-2!

Has anyone tried 45 Super out of their G-21 longslide? The ballistics would be very interesting. Especially the Express ammo that is designed for 6 inch barrels. :cool:

That is one nice looking setup. I was happy with my Glock collection until I saw this longslide and now I NEED one. Very nice indeed.

So Mossy is saying that the weight of the slide keeps the recoil down? I had thought that the weight of the slide was a very delicate ballance and could not be changed much one way or the other.

Examples may be like the 17L doesnt weigh much more than the regular 17. And that they had to remove material from the top of the slide to get it to cycle.

Would adding one of the weights to the front rail accomplish the same effect?

I want to get a 6" bbl for my G20 but hate the way it looks with the barrel hanging out that far from front of the slide. Rather than paying $600 for a slide (more than a new gun), I wish someone would make something like the H&K barrel shroud/comp. If I had a machine shop I would make one but don't have the tools/skills. I'm sure they would sell.. Anyone want to try making a one?

Mossy Oak & Rawny,

What type of guide rod and what lb. recoil springs are you using in your long slide 20/21?

Rawny

08-23-2005, 21:36

Dan and Hawk,

I'm inclined to think adding a weight like this:

http://www.topglock.com/images/GLOKWEIGHT.JPG

or putting on a barrel shroud would not have the same effect on felt recoil. Your slide is still stock, and will cycle as it has always been. The extra weight will reduce muzzle flip, and can help you get back on target a tad sooner.

When I shot my long slide for the first time, I had just shot a couple of mags of .45 with the G21. After the switch, it felt just like I was still shooting .45s. I was not shooting weak stuff either, they were GA 180gr Gold Dots. It felt much softer than my friend's G20.

ColoradoGlocker had actually suggested I use a lighter 15lb spring. I planned to shoot mostly hotter loads like GA and DTs, so I used the heavier sprung stock rod, it worked fine.

That would be a nice option! I like that idea.

Rawny,

That just does not look like a very good design. No offense to you but heck, I could take some lead weights and make something that ugly. ;f ;f ;f How do you even holster that thing.

:soap:
We are Glock owners... we need something functional and cool looking.

Perhaps a mold can be made from an M3 light, and turned into a lead weight. There are holsters that accomodate a pistol with an M3 attached.

That would be a good idea.. the more "Universal" it is the better it will sell... (Glock, XD, HK, 1911's, etc) Anything with a accessory rail.

Me too! I would love a longslide G21... But dang!!! That is an awfully steep price for a slide.

Have you shot groups with it yet? How accurate is it?
thanks

i came upon this recently, an article from the C&S site claiming that *lightening* the slide reduces recoil and muzzle flip. like they use heavier springs to reduce velocity, and the lower mass doesn't kick as hard.

Is it accurate?

Mossyrock

Is it accurate? Yes. In some cases scarily so.....with ammo it likes. The mass of the heavier slide begs for power. If you feed it low power ammo, it will balk and give you patterns. If you feed it 180-200 grain ammo over the 1,200fps mark, it will give you .90" (smallest) to 2.00" (largest) groups off of a bench at 25 yards. If I ever get a chance at both the loading bench and the shooting bench, I will try for some 50 yard groups for record. Heck, if I am feeling adventurous, I will give the 100 yard line a try..... ;f

Anyone chrono any .45super out of the longslide?

I am really thinking about taking the G21/20L plunge and I would want both the .45-10mm barrel and a fully supported .45 barrel for occasional .45super use. It would make an AWESOME hunting and woods sidearm. Not to mention just plinking.
