I was lucky to find a 6-1/2" and 10-5/8" barrel M29 with the adjustable front sight. I am not impressed with the front sight because it doesnt hold zero from recoil. 10-5/8" barrel is VERY muzzle heavy shooting with 2 hands.

I have an 8-3/8" barrel 629 that is much simpler to shoot, for example: 50 yard zero, +2 clicks 100 yds, +3 clicks 150 yards, and +5 clicks for 200 yards.

The adjustable front sights don't have 'clicks' on the set screws so adjustments can be a challenge.
