Mechtech glock

[TerrorDactyl]

I have recently gotten a 9mm Mechtech upper for my gen4 glock 34.

When I fired the first 100 or so rounds there were no feed issues but then it started stove piping early in the mag an close to finishing the mag.  It was both with after market and glock mags.

I sent it back and factory said they found no problems and returned it with a few of the cases they had fired.

The first time I fired it was with a factory mag and it stove piped on the third round.  It has had a misfeed on every mag used except occasionally it will function with not having an issue for a whole stage but has only happened once in 10 stages.

I am curious if this is just my luck or if the misfeed could be a regular happening with the Mechtech.  I did tell the factory that I had a gen4 and they said no problem.

What does the real world say.

Did they use your mags or their own when testing?  That may be the difference.

Are you shooting factory ammo or reloads?

My experience with the MechTech carbines is that they like hotter ammo. They can be finicky, but run great with ammo they like. I can’t see the Gen 4 being any sort of a problem.

If the pistol is cycling ok with your mags, It would lend me to believe that your ammo is the problem.  Are you shooting factory or reloads?  have you tried different ammo in the gun?

Hello: I have owned 3 Mech Tech Glock 17/34's. I still have one and have used it with a Glock 17,34 and gen 4 34, all have worked perfectly. I only use factory Glock magazines with it also. Sounds like an ammo problem or magazine problem to me. Thanks, Eric

I had similar problems back in 2011, sent the upper back for refund. I was using factory Glock mags and FMJ rounds, both reload and factory.

I have been using both factory and after market mags I have not used reloads yet.

I have had trouble with 115 gr rn

Federal, Winchester, Freedom

124 gr RN

Freedom, Wincheter, American Eagle 

I just got some 147 great RN Freedom that I am going to try at the range tonight in a USPSA shoot.

I hope this fixes it or will either get it fixed changed out, or try to sell it.

are you using a 32 rounder or a G17/34 factory mag?  do you have tension on the extractor?.... the single wire extractor spring may have moved or broken

[TerrorDactyl]

Well tonight it stove piped three times on one mag with 147 gr RN

A friend that has one as well saw it and noticed that the e clip that is supposed to hold the return spring on the firing pin was gone and thought that mght have been the problem but we did not see any excessive dent or hole in the cap on the errant cases.  

I am going to see about having some sent to me as that is what they did for him.

I also noticed the exterior return spring that holds the barrel and firing section together is now disformed on the bar end of the big spring
