Range Report
I finally got to shoot the 4563. We were VERY busy all day, till around 10 minutes before closing. So I had to use a lane that "broke" yesterday. Someone hit the travel rail, causing the target carrier to not go beyond the 10 yard line. But that worked, for me, as I was tired and didn't have my range bag to rest the pistol on.
So I ran 4 mags - 32 rounds - to test for function and check that POA = POI. I used 8 rounds of S&B 230 ball, 8 rounds Sig Performance 230 ball and 16 rounds of Federal HST 230 JHP Standard velocity.
The gun ran 100% as expected. I had done the "pencil test" after cleaning to check for function and it had launched it across the room. Ejection was good, throwing everything up and over my right shoulder. I ran the S&B first. It went into 4" with 1 flyer. The Sig ball did a little better ar around 3.5", again with a pulled shot, from me. The HST grouped best, as expected for premium defensive ammo. Both groups averaging around 2".
I am VERY happy with the rail free 4563TSW!

-Thank you again vigil617! It will go in my holster when working the range and also get carried a lot this winter.
I may change the grips out to the thinner OEM Delrins with a rubber grip sleeve. The Hogues on it now felt....thick, to me. I had to keep adjusting my grip in between mag changes. All my 3rd gen carry guns wear OEMs with the rubber sleeve set up. It anchors them in my hands better. And enables me to shoot tighter groups, faster.
Of course the trigger is a primary considerstion in an accurate pistol, despite what you may read elsewhere.

The trigger on this 4563 is great. Very smooth with a crisp let off in DA and SA. Short reset like every 3rd gen. A couple of the younger guys working with me tried the trigger and were amazed by it. Their exposure is only with plastic striker fired guns. They had never experienced a good trigger. I teased them that I was old enough to remember when manufacturers strove to give handguns a good trigger right out of the box, without having to resort to aftermarket to obtain one.
I intend to spend more range time with the 4563 when my schedule slows down......if it slows down. With the tragic election outcome I anticipate a high volume continuing at the range and many more private lesson students on my days off. Ammunition availability appears to be going to get worse. But between the police supply and the instructors ammo discount I have managed to put up enough ammo that I can still shoot a few hundred rounds a month. And the next few months will be used familiarizing myself with the superb 4563TSW. Regards 18DAI
