This will be my next toy purchase!!!

Been watching all I can find in uTube! I'm sold! Now to work out the extras, buy a couple four hi cap mags and find a dedicated lower as I want a carbine all the time + my G20!!!!


Momma and I just bought new computers for each of us, so this will have to wait till next spring or so, but it's gonna happen!!!!!

How is the weight? Relatively light? Ive heard that these vibrate a lot and make a "twang" sound when the bolt cycles. Is that true? Im trying to decide whether to get one of these or sbr one of my glocks for use with a hera arms kit.

watch my mech tech youtube videos and tell me if you hear this "twang".

I'm about ready to make another one on how much the bullet drops between 100 -200 yards. looking to take it with me to Wisconsin in Nov. for deer season.

Has anyone used a G21 lower for a 10mm mechtech upper? Does it work?

Yeah, they "twang". My son has one for his G22/.40, and it twangs. Twangs like a Daisy Red Rider. He has 1000 rounds through it, and if that's the "worse" it gets, let'er twang!

So far, it eats anything its fed. Dead-nuts accurate out to 150 yds. with factory power rounds. The red/green dot sight they sell is very effective.

And the weight.... They're heavy out front. Heavier than other "black rifles". No problem though, punching out 30 rds at a time. Don't even notice the weight. You can slim it down some, if you pass on all the accessories hanging on the front (rails, light, etc.).

They (Mechtech) say it will work, and it should. G20 and G21 frames are identical. The same is also true for other "like" frame platforms. The website lists acceptable compatibilities.

Mech Tech

There is a way to keep it "pistol" fellas. At least here in Michigan. UTG makes a folding stock adaptor. i think it is called the model 47 side folding adaptor. It was $20 shipped to my door. With this in use, the Mech Tech is under 30" in total length. It can also still be fired from the folded position. And barrel is 16". By Michigan law, im gonna wack and stack the deer with my registered Glock 20!!!!

dm1906: Also i am curious as to what factory ammo you are using that is "dead nuts" out to 150 yards? I myself handload some very hot 180gr XTPs. It is dead nuts out to 100 for me all day long. At 150 it still throws one hell of a group. But it is low by about 6-7 inches. I have found the 10mm, as most pistol ammo does, drops pretty fast after 100 yards. I believe thats why people say pistol caliber carbines are good 100 yard guns. With correct hold over i have become very good out to 150.

drsjr1969: I would be interested to see if your results from 150-200 yards are the same as mine. Please report.

I'm always concerned about the amount of excess slide-rail wear the upper would impart on my G20 frame.... and since I've not seen these in person, I don't really know how to answer my own question: does putting on- and taking off the upper take a lot of force? Is it a very tight fit? Do you think putting it on and taking it off could induce more than a normal amount of wear in these places? I'd hate to shoot this upper a lot and then change back to my stock G20 slide and find that its fit is even sloppier...

Anyone?

Not at all. With my slide already off of my G20 frame it takes me all of 3 seconds to do.

Is it a very tight fit?

Nice and tight fit they way you would like it! In fact it is as good of fit as my Colt AR 15 upper to lower. No rattle or movement from the 10 or so different ones i have handled.

Do you think putting it on and taking it off could induce more than a normal amount of wear in these places? I'd hate to shoot this upper a lot and then change back to my stock G20 slide and find that its fit is even sloppier...

NOPE. I and many others i know personally have put thousands of rounds through our Mech Techs. And pretty potent ones at that! Still goes on and comes off as easy as it did the day it was brand new. Fit hasnt changed a bit after going back to the G20 slide. In fact the Mech Tech fit to frame is better than the Glock slide fit to frame.

Anyone?
In all honesty i have probably put as many rounds through my Mech Tech as anyone out there. Yes, that is a LOT! I actually could consider myself obsessed with it at times. When it comes to a 10mm Carbine, the Mech Tech is VERY hard to beat!!

forgot one thing!!

Almost forgot.... And i only speak of this for the Glock model Mech Techs, as i have never handled the 1911 version.

But... with the glock models, there is no movement on the rails of the frame. It actually is held on by the rails and locked into place much like your slide, except the movement is all in the upper part of the Mech Tech itself. Imagine the upper of an AR-15 platform. Very similar. I believe this should help you to answer your question. If not sorry for the confusion. I tried...

No slide wear. As said above, once locked in, all the firing action is in the upper. The lock is against a hard rubber block, so it stays tight once locked. The Glock frame is only a feeder, handle and trigger. The "Glock Block" (fits over the locking block) is the ramp that feeds rounds to the chamber from the mag.

My son's G22 was a police academy whore for years. Probably in the neighborhood of 30K+ rounds through it (just a guess, as it's probably a lot more than that). It's all original, slide is still tight, and it shoots as straight as any.

Since he got his, the 10mm version made it to my short list....

Accurate, as in, repeatable, consistent accuracy. It drops, of course. Curious, we found, is the POA is very close at 50' (originally sighted) and 150 yds. It would likely be very different if sighted at 50-100 yds. I don't have anything previous to base it on, so we're still building data. I'll have to work the trajectory calculator to confirm, but it's on, none the less. All the distant shooting was with the dot sight, so the peeps may open up a bit. I may have to try a scope, just for S&G's. The weapon shoots straighter than the shooters, for sure. Ammo is handloaded various bullets, loaded to factory velocities. Coming up will be some dedicated carbine rounds. Slower powders that don't normally work ideally with short barrels.

Also quite EXCELLENTLY worded information on the mating dynamics. Thank you, dm...

Yes, its definitely on my short list... MMM man, I'd love a setup like the one on the first page.

Sounds right. I have a good, easy to use tool to run that trajectory if you don't have one... But I suspect you do.

I wonder how much extra velocity handloading can get the 10mm up to...

I do. I don't have a lot of interest in the .40, and really don't want to start another project. In the meanwhile, the damn thing is like peanuts! Just can't stop shooting it!

THAT is on the agenda. There are limitations to blow-back action, but not something I can't work with.

But would the limitations to blowback (in a carbine) be any more serious than the limitations created by, say, a stock G20 barrel?

Probably not. :-) which means you should be able to wring more velocity out of the setup...

Actually, a lot. I've been down this road before with other cartridges. I'm looking forward to it, but it'll be a couple months before getting started.

Well, the Glock / 1911 / BHP designs are not blowback.. .and I get that... BUT ... I'd think that you should be able to exceed 6" barreled loadings' velocities quite easily, and maybe even by a large margin.

Time will tell!

Without a doubt, by a large margin. The 16" .40 is already faster than 10mm in a 5.2". Both loaded to moderate (factory) levels. So far, the comparisons have been basic and unscientific. We'll start gathering some real data, once he gets about 1000 rounds through. It should be about as broken in as it can be, by then. Any minute, now....

What are the options for a dedicated frame.. (lower)

I like the idea of switching but may just want a dedicated carbine AND my G20...

Rather not buy a complete gun and have a barrel and slide hanging around... Altho O have been wanting a G21...

I can tell you at least that it will push a 180gr cast bullet over 1500 fps, probably 1600+ with the right load. That's just based on what I've been able to do with a blowback .40 in a 16" barrel.
