I have a 9mm pistol, I just got done with, and I’m having problems getting it to run. Lots of stove pipes!
New Frontier side charging upper
Kaw valley precision ramped 9mm bcg
5D 9mm lower
Mil-spec lpk
Mil-spec carbine buffer tube
Ballistic Advantage 8.3” 9mm barrel
Kaw valley 7.5 oz 9mm buffer
Springco Red carbine spring
9” m-lock hand guard
KAK ind. flash can
Wolf 115 gr steel case junk
And of course, my only 9mm magazine (ETS 40 round clear mag)

When I hand cycle it, it is flawless.
Yesterday, when I first shot it, it was setup full weight, with the Springco red spring. I could only get through five rounds, maximum without a malfunction. Recoil was sharp.
The type of malfunction would be failure to extract...it would stove pipe, the spent case, and try to load another round.
So, last night I removed the weight from the bcg, and started fresh.
Today, was about the same...malfunction, but seemed to recoil less without the weight.
So, I removed the Springco, and installed an SI flat wire carbine spring.
With this set up, it was a single shot, stove pipe situation.
So I figured, I’m going the wrong way.
Anyway, now I’m wondering what to try next?


Should my next step be to buy an actual Glock 9mm magazine?
Or, is the ammo just junk? I mean it does seem like the ammo could be too low of pressure, to actually cycle. But the mag was cheap, and it does really seem like junk.

Thanks
