More from that article:

I have one 303 that I have shot a ton. Well, over 90K according to my log
books. The only modifications I've made to it have been to get Allan Timney
to do the trigger. I also used his hardened hammer struts and link.
Additionally, I use a magnum recoil spring in place of the standard one. I
replace the spring every 5~10K. Other than that, the gun just chugs along.
I've replaced most of the parts (including a couple of bolts) over the past
15 years, but nothing approaching what I had to put into my 1100s. My other
identical 303 is virtually unused as I kept it for a spare and never really
needed it.
