45 acp hi-cap mags

I didn't see this topic after doing a search, which surprised me:

Which .45 acp hi-cap 27 round magazines are good?

I have some oem 9mm 33 round mags and I enjoy them.
As far as I can tell, no oem .45 mags exist.

So, which aftermarket manufacturers do you use?

Thanks for your suggestions.

KCI only, others are unreliable in my 4 yr quest for a reliable hi-cap glock 21 magazine. With KCI I have had no malfunctions other than the known limp wristing.

Factory G21 mag with the Kriss extension.
As I go through life I keep coming to the same conclusion, people are generally stupid.

I tested 5 of the Korean 27 or 28 round mags. Not one went without problems... ranging from falling out of the G21 SF after each shot or massive FTF's.

Many could probably be fixed with a little... or a lot of TLC. I did use a razor knife to define the edge of the retention slot on the one, but left the others alone and re-sold them. The best one went 23 rds before 1 FTF and then finished up. The worst had many FTFs.

There's ONE good answer to this: I just got a bunch of the Kriss magazine Extension Kits made by Magpul. I put several together and tested them at the range. They work great! I may actually use the Mech Tech Carbine Conversion that I assembled and have tried to sell becuase I couldn't shoot it at the range I belong to... only long guns allowed are .22's. They're about to finish a 25-yard range that can handle rifles, so that and a reliable high-capacity magazine for the G21 SF-based carbine may make it a keeper for me.

I've since put together 5 more Kriss 30-round mags for resale at the gun show this weekend in Jacksonville at the Prime Osborn Convention Center. My wife and I will be vending there and we have a lot of Glock mags... just about every one made... standard and hi-cap, as well as the new Kriss conversion Kits.

I don't know if there's a venue for this kind of post, but if I've broken any rules, monitors please put this where it belongs or delete it.

It's not my intent to answer posts on the kits' availability or try to sell them here... just information. I have to get ready for the show and go set up our table this afternoon.
