Smith & Wesson has been neglecting revolver production for many years. Simply because demand across their market (which includes law enforcement sales) has favored their semi auto pistol product. Pistols are typically easier to manufacture and generate more profit per unit. In the past decade, revolver production has been approximately 20-25% of their production. The Covid era problems may have dipped revolver production lower. Combined with 2020 panic buying, you might find the answer to be found in higher demand for revolver product at a time when supplies were low. Smith & Wesson still offers a pretty extensive catalog of revolver product, and I can imagine that keeping them all available for distribution would be a challenge. Just now, I checked Gunbroker and there are scads of new Smith & Wesson revolvers on offer there.
Unfortunately, I have to agree. The last few new Smith & Wesson revolvers that I bought all came complete with nagging quality issues. In spite of being made on modern CNC production process. Which supposedly lowers the probability of human error in manufacturing. Yet introduces new avenues of error.I love LOVE LOVE my s&w revolvers, especially J and K frames, but I will not buy one online because I had too many issues with their QC, and what they allow out of the door.
