Now that looks sharp! Do you recall the type of wood those are made of?
Btw I'm new here and haven't owned my 10mm SR1911 that long either so I could be wrong about this but you may want to do some research about possibly changing out your recoil spring for a heavier duty one.
It's on my to-do list personally. And again, I could be wrong but after seeing references in threads to more than one SR1911 10mm with a cracked lower barrel lug, I started to suspect that these guns might be a little undersprung by Ruger to function with most watered-down 10mm ammunition. I emailed Ruger about it and they told me that the stock recoil spring is 18 pounds which seems too light. If I'm not mistaken, Wolff Gun Springs lists 19lbs as stock in 40s&w Colt 1911's. However, it is possible that the Ruger's bull barrel reduces the need for heavier springs. But personally I will err on the side of caution and try out a 20 pounder if only to prolong the life of the pistol, maybe even start using those little Wilson Combat polymer buffer dealies.
