Long story short: Yes, worth the extra money.
I'm trying to remember back when I went through this. It's been like 6 years. So memory and going through email history isn't quite perfect.
by the looks of it I went through 2 ProMags before I resold them and bought one for twice the cost.
I want to say the Promags were $45 and the new one I went to was $80. I can't for the life of me find what and where I got that one from.
$187.02 with code builder15 and the top loading version is $162.79It's now $216 woof.

Also looks like they have other versions that are more money. Dedicated models. Mine is designed to come in and out so i can swap with a 300Blackout upper.
I haven't had any problems with the Hahn since I went to it. Locks in place with a little allen head set screw
The Hahn mag blocks are among the best available, everyone else copies these.
The bottom loading block can come out when you don't expect it to, so its not recommended for a use where timely magazine changes are important. The non-dedicated top adaptor is their least expensive offering and you only give up the last round bolt hold open -which itself is only as reliable as your magazines. I have an estimated 100 thousand rounds through one of these
Toolless drops in from above, while "dedicated" can only be installed/removed by also removing the bolt catch.I can't tell the difference (other than $25) between
- "AR-15 Top 9mm Adapter" : AR-15 Top 9mm Adapter
- "AR-15 Dedicated 9mm Adapter" AR-15 Dedicated 9mm Adapter
TBH, the MEAN EndoMag® is a lot easier unless you have another reason for using standard-capacity colt mags (ban state, already own a bunch for another gun, etc).

For anyone who's following along at home:
I decided on the "dedicated" adapter from Hahn Precision. I talked to the owner on the phone (I think he was the owner) and he was super helpful. The "Dedicated" version has the LRBHO thingie built in, and it's more sturdy than the "top loading" one. He said if you're not going to swap configurations all the time, the dedicated version is a better product.
I haven't installed it or anything yet, but it feels really solid and like a ton of engineering went into it.
I really like this little detail: (for those of us who have a bunch of metric and English tools)
