I have a 689 and the lock up is very good on mine comparable to the 586 I did have, also I have no trouble cleaning powder residue off the 689 and I use Bullseye powder.
I finally got to shoot my new Taurus 689.
Taurus Model 689, 4" barrel, .357 Magnum/.38Spl.
Im always on the lookout for guns at great decent prices that deliver great performance. Check this one out!
