MK9 v. MK40 <> (?)

I looked at that one, but found two problems: 1) I couldn't find confirmation that it accepted H&K pistol magazines.
Bottom line: IMHO, send your Glock back.
Why should everyone else get to own an engineering marvel when you have to put up with an occasional failure?
Like I said, let them figure it out.

Believe my SP5K will only run with MP5 mags.
It's really a civilian MP5.
And when I bought OEM mags from Hk they were actually MP5.
The curved 30 rounders are not cheap and run ~$70 each.

As for the Glock, I'm no armorer, but FTF is usually RSA or mag springs (already changed out).
Strange thing is it ran fine with OEM 40 Storm Lake 40-9,357,40 up to around 6K on the clock.
Then occasional FMJ FTF with all barrels?
The only stinker was the jam o matic OEM G33 357 barrel (with G33 mags)
That POS FTF nearly every mag from day one (and was my reason for going with Storm Lake).
Only thing I can think of for FTF is polishing the feed ramp and/or opening the chamber?
Maybe at 6K it just needs an overhaul/tune up?
That seems to be what Bawanna is recommending?

I really like the Scottsdale Gun Club gunsmithing service.
Maybe I should break out the G27 and give it to them for a complete repair/replace everything?
Go back to bone stock 40 or 357?
I'll think about it.
Really hate having a gun I can't trust

Update:
I've decided to go with;
1) AlphaWolf Stainless Steel LCI 9mm Extractor,
White Sound Defense High Reliability Extractor Depressor Plunger Assembly for 9mm
and a OEM 9mm trigger housing/ejector.
2) Using my Storm Lake G27 40-9mm stainless steel conversion barrel (it's a tack driver).
3) Have Scottsdale Gun Club inspect and replace any other worn parts.

Maybe I can make this dog hunt after all
Thanks for the push guys!

Update 2.0:
Dropped off gun and parts at the gunsmith.
Having the Storm Lake barrel throated and polished as well.
Gunsmith is confident he can make it run right - Woo Hoo!!!

The gun is a TALO EXO exclusive G27 with a nickel boron Fail Zero self lubricating slide.
The Storm Lake 40-9mm barrel is stainless steel and looks like a Bull Barrel in the gun.
Gunsmith commented on how nice it looks.
I'm beginning to believe this story is going to have a happy ending - LOL!
