Servicing Glock Slide With Barrel Installed, Doable?

[arakboss]

I have just about given up on finding a reasonably priced 16" barrel for my 9mm/40 Glock Rifle project.

A cheap alternative would be to buy one of these barrel extensions and silver solder it along with a muzzle device to a regular length threaded barrel.

Home :: Muzzle Attatchments :: 4in 5in 6in 7in 8in 14-1LH & 1/2-28 Pistol Barrel Extensions

These barrel extensions are made from steel and have an inner diameter over 400 to work with any pistol that has either 14-1 LH or 1/2 -28 right hand female threads Permanently attach to your pistol or SBR to bring the barrel length to 16 Our extensions have a 5/8 -24 male thread on the end to...

The downside will be that the barrel assy will no longer be removable from the slide. Would this prevent any repairs from being done to the slide itself?

I have an extra Glock 22 slide and a 5" threaded 9mm conversion barrel on hand so this project could be accomplished for about $50ish dollars (excluding silver soldering cost) in additional parts.

Quit while you're ahead.

Pay the $200 tax and SBR it, you'll be money ahead.

And just how, exactly, do you plan on lining up traditional rifling perfectly to the polygonal rifling AND the bores in alignment? This is a terrible idea and I can't wait to see the results

Please do it.

The barrel extension I linked to is .4" smooth bore. No match up of rifling necessary.

Why? What's the point….

You must be new here. Arakboss doesn't often have a point, he just dickers with stuff because he has the attention span of a gerbil. You really should look at some of his projects to get the idea

If they are anything like this I think I'll pass….

Gonna agree with the "just SBR it" solution. It sounds like you are just going to have a ~12 inch muzzle device on the end of a pistol length barrel, so you will be getting no benefit from all the work, and that is on top of not being able to disassemble the gun. If you SBR it you can still use after market 6 in barrels and get some utility from a longer barrel, while being able to swap back to a shorter barrel if you run into reliability issues from the added barrel mass.

But there is rifling in this extension, .4" smoothbore isn't enough to stop that spinning projectile from spinning before engaging the extension rifling, I think. Can't even begin to image the torque placed on the joint of original barrel/extension. Thinking one shouldn't expect much accuracy as a result of engaging the second set of rifling in the extension.

Sorry, just can't wrap my un-caffeinated mind around the physics involved.

The barrel extension acts the same as a fake suppressor or many other muzzle devices. I slipped a piece of copper tubing over a glock 40 barrel and it didn't budge.

DO IT!!! I haven't seen a "franken gun" for a bit.

Is that your goal? To avoid a tax stamp so you can put a "stock" on a glock….

I wonder how long that would last if you just soldered that onto the end of the barrel? Seems it would be worth it to test if all you wanted to do was avoid a tax stamp. I know copper is soft and you would eventually have to worry about erosion at the muzzle, but I figure it should last at least a few hundred rounds before you need to solder on a new extension? And you could probably get the slide off to boot.

The term "retarded" applies here.

I can get the barrel with this copper pipe combo out of the slide because I am running it in a Glock 21 slide.

This set up needs a smaller frame Glock to work.





Reason for rifle length barrel is to make it acceptable for use at rifle only range area.


I have a dream. One day, the how will be more important than the why.

I do want to pay for a tax stamp when it's not necessary.

lol. Whatever floats your boat.
