In KY, it's legal to hunt deer with any centerfire cartridge in handgun or rifle. So legalities aren't a problem, even with the .45 if I decided to go that route. The barrel on the Witness is 4.5" or slightly longer. Not quite 5" of a full-size auto.
As of last Friday, my package from Midway came in. I immediately installed the 22lb recoil spring, extra power firing pin spring, and +10% mag spring in my Witness. I then started working up some loads with 800x and Power Pistol for 165gr Gold Dot and 200gr XTP (for hunting). Factory fodder can't touch full-power stuff, period. I'm still working up loads, but I hope to have about 50rnds of 200gr XTP over 9gr of 800x soon. My selection for a deer load. I'd go further with a chronograph, but I don't want to push my luck without one.
On Saturday I went to the flea market and found this guy outside with a few tables loaded with nothing but ammo and a couple handguns. So, just casually browsing I found a box of Winchester Black Talons in 10mm (200gr SXT, see avatar). I paid $30 for the box, but I got it mainly for collecting and won't shoot it. Still, looks like I did good considering people online are selling boxes for $40-45.

Last night I got to work doing some smithing on the Witness. I polished the device that lifts the trigger bar and the rod it rides on. This made the DA much smoother and removed any grit. I then went a few quick passes over the sear to smooth up the surface a bit. I also cut the ejector down a bit to reduce the flying brass, but that's something I'll still have to play with. I'm also considering the EGW sear for this gun. You lose the firing pin stop, but it might help improve the trigger even more.
After that was done, I looked into fitting a set of Hogue rubber grips I bought for a small-frame Witness (they don't make them for the full-size). I'd heard you could stretch them (and did I ever) only to find out portions of the plastic didn't line up right and prevented the mag from going in. After a lot of sanding and filing on the grips, they fit fine now. My only complaint is the protrude slightly past the rear of the frame. Nothing a hit of sanding can't fix, but it isn't enough to warrant any action at the moment.
I'm still debating on a chronograph. I'll let you guys know if I get one so that I can put tangible data to the loads I'm working on.
