Hey all, shot my new 851 yesterday for the first time.  I got this piece to be my new carry gun.  I only put one box though it but have to say that I'm really happy with it.  Fit and finish is way too good for an inexpensive gun.  The trigger pull in single action is great, very clean break.  The double pull is long and smooth.  Both DA and SA I was able to hit cans and my swinging target better than half the time at 10 yards.  The cylinder lock up is very tight, no shake, very tight gap.  

Overall, one heck of a good shooter.  Now, to get a good holster.
