Remington 23728 UMC Full Metal Jacket FMJ 115 Grain 9mm Luger/Parabellum - 1000 Rd - $199.99

Sorry. My error. In my senility I overlooked your "lightweight" spring use. Those springs would certainly throw some codes and cause all sorts of experimentation. I'm still curious why the 124 Rem fails when the factory specs list identical velocities. Maybe the test barrel was longer. I'll have to chrono some. I have probably 15-20 9mm's on the rack, mostly alloy Sig and Beretta, some CZ and HK, Glock, S&W, FNH, etc., in hammer, striker and external extractor 1911 designs, use only duty weight springs, no subs or suppressors, no steel case, and don't shoot them as much anymore. They tend to be boringly reliable with major brands and reloads, with accuracy as the only variable. The Blazer was the only brand causing problems, and that out of a stiff M17. Oh, and a S&W SD9 which was such a POS that it became a test dummy.

Remington 23728 UMC Full Metal Jacket FMJ 115 Grain 9mm Luger/Parabellum - 1000 Rd - $199.99

I can get it to run in a cz. Not in any striker fired pistol with their more radical cam. As you go to lower spring weight in striker fired other problems are introduced. I've tried. I've got 5 k of it.

With the 19 with factory spring it has failures to feed. Slide does not go fully to rear. With a 16 lb spring failures to go into battery. Say every fifth round.

If you go lighter in recoil springs with a Glock you have to lighten firing pin spring...not really wanting to go further down rabbit hole. I just wanted some range ammo not to respring my guns.

PSA micro is more or less same. Bought lighter springs for it too trying to get it to run.

Same guns run like sewing machines with Speer lawman or S&B.
Here is one discussion about UMC low power factor.
I was surprised used many UMC components over the years and they were fine. Still use many rem components.
I haven't chronoed it don't really care. Does not run in my primarie

Gonna take it gun show and dump it.

Care to share the firearms it runs in for you?
