Haven't had too much time at the range but it does feel much better. My finger doesn't hurt after 100 rounds or so. I like the 35% less travel compared to the stock. Right now I have a failure to feed issue which might be related to the type of ammo I used. Won't know until my new ammo is shipped out. My advice is make sure your gun is fully working and reliable before you do the trigger kit. Get a good gun smith. The gun smith that did the trigger install didn't put any loctite and didn't adjust the rtk trigger correctly. I ended up taking it to the place that I purchase my gun and they did the adjustement for free.
I wish I would have waited. Now I can't send it to S&W for service unless they can promise that all my trigger kit parts will be sent back or kept in my gun.
