I received my witness p carry last week and I finally made it out to the range. I had two issues pop up the more concerning one the safety no longer locks the slide it does lock the trigger and hammer l. The other is I have nose up jams with high impulse rounds with the last round I tested to see if I put a weaker round in the second to last it would run fine.
Yes...The safety on the witness does not lock the slide. Just the trigger and hammer. I personally like this feature as it allows be to load and unload without taking the gun off safe.
Nose up jams are due to the higher slide velocity with the heavy rounds. It can be mitigated first/best by a flat bottom firing pin stop from Hennings.
I for some reason thought it locked but it doesn't bother me. I fired 300rds a mix of pmc armscor georgis arms and unserwood, it only jammed with underwood. I did some testing with a mag of underwood and used a pmc for the round before the last which worked. I already installed the henning upgrade kit minus the guide rod.(doesn't fit)
If you already have the henning kit in, you are about as far as you can go without upping the recoil spring rates. I run a 22 lb in my Witness guns. A little more slide mass would be ideal, but is counter the idea of the poly frame and over all EDC lightness.
Does it use and have K10 mags?
You will need the shorter guide rod if it's the 3.6" barrel.
I thought possibly a stronger mag spring would help. I may up the recoil spring but I can live with a weak round in the mag, it still holds more rounds and is lighter than my 1911.
It does use k10's but the slide is a compact so the 3.6 is too large.
I had nose up jams with EAA Witness P Carry 10MM 3.6" Polymer using Winchester 175 Grain Silvertip ammo.

Just an FYI - I just emailed Henning, and he's currently out of flat bottom firing pin stops:
"I ran out of them. We might make them again later.
Thanks
Henning"
Guess we need to start putting in requests?
