The second issue is the rear slide plate is VERY difficult to remove requiring plyers. I noticed when using the punch to depress the striker, it barely moves. I thought it was the slide plate being out if specs but I ordered a new one at it seems just as snug, so I reinstalled the old OEM plate.
My altimate plan is to take the 23 to a GSSF event and have an Armorer take a look at it. But most GSSF events in my area are canceled or delayed.
