I had an early SR1911CMD (4.25" .45ACP). Two front sights fractured/broke-off while shooting. Each front sight lasted ~5K rounds before breaking. Both front sights were replaced by Ruger taking about two weeks each time after sending Ruger the slide. The 3rd front sight was doing fine when I sold that Ruger.
The elevation on my early Ruger's sights were not regulated well. I later heard Ruger changed the front sight height on later Rugers but I didn't get any of these newer front sights. To compensate for the elevation, I'd bought a Novak adjustable rear sight as found on Ruger's website. This rear sight subsequently had its adjustment screw strip out while firing sending rear sight parts flying with some parts never to be found. I bought another adjustable rear sight which was doing fine when I sold off that Ruger.
Accuracy-wise, this Ruger never grouped well enough to my liking compared to my 5" 1911 guns or my Glock 30SF. I did replace the barrel bushing with one from EGW (some fitting required) which tightened my groups ~50% (maybe 8" to 4") but still not to my liking. Again, so I sold this Ruger.
The thumb-safety was a bit "soft" feeling. A different plunger and spring gave me the feel I preferred.
I did like the "Commander" 4.25" size. I liked how the plunger tube was integral to the frame (cast in as part of the frame, I believe).
I do miss having a 4.25" 1911, but after nine 1911 guns over the years, I'll just stay with the three 5" 1911 guns I still have.
