We also shot a glock 22 at 200' and the bullet was big and slow enough that if u stand behind the shooter u can actually see the bullet fly to the target, the 40 cal has a higher rate of drop due to its 300 fps slower muzzle velocity. I highly Roccomend attempting this, it is extremely fun, and show what a pistol can do. Now for stopping power, I wouldn't shoot past 125 yards, but for at the range it is a good test of accuracy. Wouldn't reccomend if you can't get decent groups at 50. What made the 40 cal easier to shoot at 200yds was the fact that u could have a spotter see the bullet flying to the target, so he could give instant corrections, and it isn't easy to keep your groups consistent, but is possible to keep them I. Groups of a couple feet
