Correct answer. This gun is amazing out of the box. Tight, smooth, and tame...everything you'd want in a lady, but in your gun. Trigger out of the box is great and puts many factory guns to shame. The front sight is FO, but wide; if you like to action shoot you may want a narrower front sight. Checkering is aggressive on the front strap and factory mainspring housing. All you'd really need is a blended mag well; I currently have an unblended 1pc Nighthawk mainspring housing/magwell on mine.
Magazine wise, I didn't like how the gun perform with Wilson ETM magazines. I ended up with a steady diet of Dawson modified Metalform mags and Tripp Cobra mags. I see that Dawson now offers Cobra mags with Dawson baseplates at a reasonable price and those will be my future mags.
Perhaps the only thing I did on mine that I thought wasn't necessary was a slightly heavier recoil spring. I didn't like how light the factory provided one was (9lb?) and went to a 10lb recoil spring.
