Pistol shipped to my FFL promptly , with no issues. The process was very easy and seamless. I liked everything about the pistol except the factory grips. I wear large size gloves and could not get a full purchase on the grip. I changed out for some wood grips that look cooler also. great gun, shoots great.

I had a S&W J Frame on by bucket list for a long time. After some consideration I decided on the Model 637. One the the factors for me is having an external hammer and single action option. The purchase process with Buds was very easy and quick as I have experienced several times. The revolver arrived in perfect condition and is well made with no flaws. The action and trigger pull is good for a shock gun. I love the alloy frame and finish. This little jewel preformed very well on our first live fire. It manages +P ammo well and the felt recoil is not excessive IMO. The stock rubber grips are excellent and help absorb some the of impact. I shot with wearing thin Mechanix Gloves and they were just right and function trigger pull and cylinder release just fine. So far I have fired 60 rounds of FMJ and JHP, 125 grain +P rounds. My first 5 rounds out of the box where rapid,10x ring shots on a B-27 target at 3 yards. At the ten yard line my groups were about 2 inches and head shots were not problem doubt or single action. I an very happy with this little "ace in a hole". Smith & Wesson has never let me down.
