Just interested, with such a high round count have you had to replace the locking block yet? From what I understand the locking blocks typically start to see breakages around the 22,000 round mark.
Not that I am worried about the locking block but I have a spare one as well as a few trigger and recoil springs put aside. I actually keep certain spare parts for all my pistols in including mag springs.
I replaced it at about 30k rounds because I was told that it would eventually break. At that time I also replaced most of the springs, just for the hell of it.
Honestly, that gun saw next to zero maintenance for most of its life until that time.
