I purchased one last winter, and just this morning finally got to the range. 200 rounds as well, perfect operation. I did strip it and lube it a bit before taking it out.
I agree 100% with your assessment. Please post up if you do the mag release swap. I have big paws and am used to the classic Sig P gun mag release. Going to go shoot it again next week and get some muscle memory going.
I bought an Alien Gear Kydex for it. It seems OK so far, I may explore other options.
