Timney now making Remington 870 Shotgun Trigger Upgrade
I guess this is for competition shooters.
Designed to work with all Model 870 shotguns, the Trigger Fix allows the user to have a clean, smooth, fully adjustable trigger pull. Every Timney 870 Trigger Fix is packaged with a sear, 3 pull weight springs and a hex head wrench. Simply choose a spring (light, medium, or heavy) and then fine tune the pull weight with the hex head wrench for a precise setting.
Price is $89.95.

UPDATE:
Shooting Illustrated has reviewed the trigger upgrade ...
Similarly, the 870 platform is just as versatile for law enforcement, those interested in home defense and three-gun competitors. Whether you employ your 870 for one or all these tasks, and no matter how your 870 is configured, Timney’s new drop-in unit will fit and eliminate the weak link of an otherwise exceptional firearm.

I installed the Timney trigger fix in my 870 Comp and what a difference. I used the red spring and set the pull weight at 2lb+. I am going to the Trap club Sunday and try it.

One of the guys that works For American Rifleman went on a deer hunt with Timney…he needed an 870 slug gun, just so happens I had one at home. They put it in for me, and let me tell you, it does not disappoint!
This might appeal to the slug hunters like places in Iowa.
Heath, good point!
