Very nice review. One of the best guns SW has come out with in a long time plus no stupid lock, I like your BH leather holster , will have to find one of those. You may want to consider changing out the rebound spring to a lighter 13 or 14 lb. It makes the trigger so much smoother and will not effect ignition.
I was going to get one but I have a regular 640 done by Gemini.
I also was lured by the 327 Federal Magnum and 6 shots so I got that one. I see by the new catalog that they no longer have it. Guess not enough interest in the 327 Mag, I think it is a great round plus it can shot 32 mag and regular 32. I reload so ammo is not a problem. I much prefer shooting the 327 Federal out of the J frame, the 357 Mag is too much for me so I load it with +P 38's.
Little brother 6 shot.
115 Gold Dots chronographed at 1289 FPS, the 110 JSP Federal are 1327 fps and the 85 gr Hydra Shoks 1337 FPS
