I've mentioned this in previous postings. I owned an early 686 SSR, which I shot very well. It had a forged trigger, forged hammer and a trigger stop. I foolishly traded it in for a mint condition Walther P5 that I equipped with a brand new set of Nils stippled grips. As much I admired the workmanship and ball-bearing smoothness of the P5, I couldn't group it worth a ***t. If a handgun is not acceptably accurate for me - out it goes. I am not a collector, but rather enjoy making really "tight" groups.
To make a long story short, my Christmas present to me was another 686 SSR. It's nice to have one very accurate revolver back in the rotation. The newer one has no trigger stop, the hammer and trigger are MIM, but the single and double action are as crisp as I remember the previous one. I've replaced the spring loaded red ramp front sight with a .250" SDM gold bead, which works perfectly with the standard height S&W sights. It's perfect now.
I highly recommend this revolver. I regret the day I ever listened to the Walther P5 siren's song. But, I've returned back to the 686 SSR and could not be happier.
Good luck with your choice.
