I really love that it's got a lower deck-height than the 407K/507K.
It's basically perfect with the CR920 sights (though I may even want the irons a little lower--as the entire rear notch is visible).
I'm a big fan and plan on buying more of these.

I want to try an OEM glock 43X/43/48 trigger housing and a good trigger like tyr/agency/overwatch in the CR920, but I don't want to spend more on it if I'm just going to end up back with my 365XL.
The CR920 certainly does feel quite a bit lighter and handier than the XL, and it seems to shoot like 80% as soft.
I'm torn because I either need to choose the CR920 or get one of the new XL slides that have a rear iron sight. I don't know if the OEM sights will be tall enough, even with the EPS, but the ZEV slide has a deeper cut and would totally work with OEM sights, but it would end up costing a lot more.
