Mine came with fixed sights, not the adjustable ones.
It has held up well, but I have only about 500 rds. through it.
I've been advised by an S&W rep that when It wears it out, and that takes 1000's of rds., not 100's, it cannot be rebuilt.
Too bad. Really nice pistol. Handles recoil much better than the 1911 guns I've shot in this rd., and is very acurate. Groups have run as small as 3/4 of an inch for three at 25 yds.
I just started using reduced power lead loads. Those are 6.8 grs. of AA 2 with a 140 gr. cast FP. My full power loads are 10.8 grs. of AA7 with a 180 gr. Remington GS HP. Both shoot the same zero.
Thanks, Kevin. The factory adjustable sight is my first choice. E
