It's a sexy beast.

I've never changed parts any more difficult than grips and this mainspring housing took like 3 minutes.
Also drifted both the front and rear sights with the aluminum punch @Water Monkey sent. The square flat sides helped quite a bit. Even so, it took persuasion in the 32 oz flavor of a ball peen. I'm definitely centered up on target better. I only ran one magazine through it today but all shots are in the 9 ring at worst and still slightly left but I'm not positive that isn't me.
