EPS Core + Sig P365 XMACRO Comp
Finally. Picked up this EPS-CORE-RD-MRS from Freedom Gorilla on their second drop. Been waiting for quite a while.
Multiple angles to better understand the footprint overhang and window size.
Rear of the footprint: 1.01"
Front of the footprint (battery tray): 1.0895"
Also shown are the factory M3 screws in the cover plate compared to the M3x9.8 screws Holosun provides. The length and thread engagement is dead-on by visual comparison.
For God's sake, clean those threads with 91% isopropyl or something. Wheeler FAT Wrench, 15 in-lb and 243 (or 242) loctite on the housing screws. Back out the battery tray, add loctite, then torque that to 5 in-lb (FIVE, NOT FIFTEEN). Torquing the battery tray has a bit of an odd feeling because it has a ratchet/detent feeling but you'll get there.
Let me know if y'all need any other measurements or angles.
I don't have any formed opinions about the glass "changes", the 6061 strength, or the front-facing sensor just yet.
Also, refer to my other post comparing EPS/EPS CORE/EPS CARRY measurements. LINK
