So, here's some stuff on the trigger kits for the XD owners in the crowd:
The Powder River Precision (PRP) Kit replaces the Striker Safety Lever to reduce trigger take-up and reset, and uses an "Easy Fit Over Travel Stop" to eliminate over-travel. They also have an "Oversized Trigger Safety" that reduces trigger movement before the safety stops it. (They used to call this the "Zero Travel Trigger Safety.")
The complete kit includes reduced weight trigger and sear springs to lower the trigger pull weight and looks like this:
You can install it yourself in about an hour, and that's taking it overly slowly and learning as you go.
The Springer Precision Trigger Kit uses a different approach, and replaces the sear with a redesigned, polished version, which reduces take-up, and uses their own designed trigger bar which can be precisely fit to eliminate over-travel.
The complete kit includes a reduced weight sear spring and trigger spring, and looks like this:
Again, you're looking at about an hour's worth of work to install the kit, mostly in slowly fitting the trigger bar to eliminate over-travel.
There are excellent reviews of both kits over on XDTalk.com.
I have one of each installed in XD's, and anyone is welcome to give them the "squeeze test" anytime you're in So NH.
Also, two excellent vendors of XD stuff are Pistolgear and XDGuys. Both vendors are known for quick shipping and excellent customer service.
Great info, thanks. How did the kits do for pre-travel? One of my gripes about the XDm is the trigger seems "squishy".. I want it as close to a tuned 1911 as possible with around 4.5-5lbs of pull.
