Accuracy

[arctic soldier]

Just shot my model 27 with for the first time in years with open sights, I recently removed the AimPoint red dot and installed a set of Millet adjustable on it. Unfortunately as I can't locate the originals which were also adjustable. My question is after installing the new sights I had planned on running through a number of rounds to get an accurate zero as I just centered the windage and guessed on the elevation. By the third cylinder I was pretty much dead on with no adjustments, granted the 27 is equipped with an 8 3/8 barrel and a target model trigger and hammer and dosen't appear to have been fired a lot. So what do you think, got lucky, inherent accuracy with the long sight radius or what? Thanks

Back in the day, when that 27 was made S&W techs used lead blocks to very, very slightly bend the frames to get them zeroed to be as close as possible to POA vs. POI with the rear sight centered. The 27 was the "Cadillac" of the S&W line, and customers don't want a gun that has the rear sight blade hanging halfway off the rear sight assembly It was the same way fixed sight guns were zeroed.

I do find it very annoying on some of my revolvers that have adjustable sights, that the rear blade is way left or right, it throws my whole aim off because I'm holding the gun cockeyed to get the front sight in the notch.......

I have a 28 that's the same way, I added a new rear sight, and I just centered the notch in the rear sight assembly and it was perfect, only about 1" high at 25 yards which I quickly corrected. It was the first gun I ever had zeroed before I even got through the first cylinder full.

I have a 3 1/2" Pre 27, that shoots into 2" at 25 yards all the time. One of my most accurate S&W's. And the smooth action adds to the accuracy.
