Which mags have you tried?

Which Mags gave you trouble and how?

Specify brand, size, and whether new or previously broken in.

Running Glock OEM’s. They have all worked except for some ban era G17’s LE marked ones. Almost like they were too tight fitting in the mag well. Fail to eject.

Shot my first 125 rounds today.

Perfect function with 3 different OEM 15 round Glock mags and one 21 round Magpul magazine.

I fired 50 rounds of Aguila 124, 50 rounds of 115 federal brass, 10 rounds of 124gr standard pressure HST, and 15 rounds of Hornady critical defense 115gr.

17 and 33 round factory. No malfunctions in around 200 rounds.

Factory glock 10, 15, 17, 33 round. No issues other than bolt failed to hold open on last shot about half the time.

I've only been out once with carbine, so it could still be breaking in.

No issues in 500ish rounds with 1 Factory Glock 33 and 2 Magpul 21's.
All mags were bought new when I got the rifle and all shot suppressed.

I would think you would get more answers in one of the bigger threads about these guns.

Careful with aluminum. I know some blowback guns have issues with it. Think Kel-Tec warns not to use it in their Sub2K guns.

Did you download either mag? Which ammo did you use and was it all brass?

Posted: 3/4/2018 9:36:12 PM EDT

[#10]

Download a mag?

Mostly Freedom Munitions and some Magtec 147's. All brass. Trying to burn through this stuff then switching to my loads.

Are you seeing or hearing issues with some mags?

MAC had issues with ETS magazines and a 50 round drum magazine.

I was wondering if the Glock drums worked.

Glock 18, 19, and pmags all run without a hitch. Sellier & Bellot, Wolf, Federal Syntec, Gold Dots +p all have run perfectly also. I put a few mags through it today sighting in my SeeAll sight.

450 rounds through mine in one session. 250 Remington UMC 115gr FMJ and 200 Federal 115gr FMJ. Used Glock 33 rounders, G17,G19
G19x, Magpul 17 and 21 rounders. Zero issues.

I guess I'm the only 1 using Ruger mags. 10 round and 17 round SR9 mags.

400 rounds so far, all Wal-Mart Winchester 115 grain FMJ. No malfunctions at all.

Might take a look @ Critical Duty, which IIRC is designed to expand @ higher velocities than Critical Defense. We need a good carbine load that has been tested in ballistic gel.

I don’t know about higher velocities it’s just bonded and built specifically to meet FBI test requirements. They wanted a load they could sell to the feds that’s it. Far as I know it’s all still designed around pistols so I would imagine the velocity is pretty close to their standard pistol ammo.

I only tried it because S&W sent me four boxes of it with my m&p rebates.

Stock 26, and 19 mags are fine, magpul failed to lock bolt back on last round but otherwise worked

On the fail to lock back, which ammo, which Magpul size? One or all of your magpuls and did it fail to lockback once or every time?

200 rounds today from Ruger SR9 17 round mags. 2 stove pipes. Ammo is remanufactured 124 Gr FMJ from a gun show. Dirtiest 9MM I've seen. I'll blame the ammo.

I had better luck with ETS mags this weekend. Only had one FTF after the first shot. Ran flawlessly after that, minus LRBHO.

Which size ETS and what percent lockback failure? Which ammo?

Finally shot mine yesterday. Ran 222 rounds of 115 grain PMC through it with only one round getting stuck on ejection.

Ran it with a 22 round ETS mag and a 50 round drum. The drum was where the issue came from but it’s a sweet shooter.

150 rds of Blazer Brass and 50 rds of reloaded 115gr HP's using Factory G17 and G18 magazines. not a single failure. Also, spot on at 25yds with no sight adjustment. I did clean the barrel and wiped down the rest of the firearm before going to the range. Will be adding a red dot in the near future. I'm liking it better than my berretta cx-4.

My ETS mags resulted in FTF issues, and one even didn't work the LRBHO. This was consistent with 115 and 124 gr, brass only. Mags were 31, 22, 17, and 15 rounds. The 31 rounder was a chore.

No issues with Glock OEM mags. 15 and 33 round.

A buddy of mine is likely going to buy my ETS mags off of me, as I'm going to get rid of them and buy Magpuls.

The Magpul 21 is a good mag. Unfortunately the 27 release is on indefinite delay.

Glock conversion in use.

OEM Glock 17 mags worked perfect.

33 round Korean (?) "Happy Stick" mags function, but the last round in the magazine causes malfunction, every time. Ammo used was WWB & Federal Eagle 115gr FMJ.

I think the 21 rounder is the perfect size magazine for this carbine, anything longer gets ridiculous.
