My experience with the Taurus M627 Tracker is that it is very comfortable to shoot - practically no felt recoil (firing 145 and 125 grain .357 cartridges) thanks to the porting and the ribbed rubber grip. However, I could not get over the fact that the instruction manuel said dry-firing would be harmful to the gun.
So I took the Taurus M627 Tracker back to the dealer after firing only 14 bullets from the 7-shot cylinder. I then bought a Ruger KGP141, dry fired it night and day for a week, and fooled a CCW instructor into thinking this tyro was an experienced shooter - by placing tight groups around the X in the middle of the silhouettes during the range time at the CCW training course.
