Just got a couple notifications that it seems a few distributors are getting them

They'll be crazy for a bit but likely will settle down soon

So, did they make any actual improvements? Or did they just change it to disallow the Glock switch? (Until someone makes a new one)

Depends on what camp you're in, really.

Glock fan? The mods include a better cruciform. In theory it's a better trigger.

Not a Glock fan? Those mods were only made to restrict the ability to use switches and such. And improvements are accidental and not what they were aiming to do.

My local shop has them in stock today. 17V and 19V both at $589
