Yup, like you, I have seen those posts as well. I decided to risk it because I really like the j-frame and wanted something better that improved on its deficiencies by offering better sights, trigger, and a lower recoil but just as good/nearly as good caliber as 38 Special. I'm sure that S&W will fix my gun, but it is bullshit that they seemingly don't give two shits about quality control out the gate.
I want the S&W Ultimate Carry revolver and the .32 H&R Magnum cartridge to find success in the market. However, given the number of problems reported on the internet with the Ultimate Carry lineup, I’m deeply worried this won’t happen at all. And then Smith and Wesson, and the other firearm makers, will blame the caliber instead of S&W shitty QC.
