I have thought a business opportunity would be to make that cut to pre Gen 5 pistols.
The cut seems to allow the extractor to hold the casing against the breech face in a more consistent manner, allowing the ejector a better shot at kicking empties out of the gun in a more consistent manner vs previous generations of Glocks. I am unsure if it also helps feeding (ala CRF in something like a Mauser/1903/Winchester 70), but it gives the gun a very firm grip on the casing during ejection. Enough that ejecting a live round takes a bit more of a brisk motion than my older Glocks.
I'm not sure if adding cuts to older guns would result in the same results, as I would guess Glock made some small changes to the extractor when they started adding the cuts. But that's pure conjecture on my part.
I picked up the +25% and +50% springs.
My G44 trigger has never been want I wanted. As I bought it as a trainer it needs to match my Gen5 G19's stock trigger. I swapped in the +25% trigger spring and it was better. I swapped in a Wolff reduced power firing pin safety block spring and it is close to my G19.
I wasn't sure where to post this, so if it needs to be moved, please move it.
I don't know anything about the company, but a buddy on a local forum was happy with his barrel. For the price, I bought one.

A cool thing I came across while browsing. G45 with what looks to be factory milled slide for 509t. Labeled as a Gunsite edition. Cool.

Here's the Gunsite webpage for the direct-milled G45 w/Holosun 509T. Unknown if Gunsite has inventory on this package.
5 PF dollars to whoever comes up with the most clever caption for this!
