Went to the shooting range to test my Glock using the NY1 Trigger Spring, 3.5 lb. Connector and Tungsten Guide Rod setup. I used new, Semi-Wad Cutter Full Metal Jacket (SWC-FMJ) rounds labeled as +P rounds, and I'm guessing they were the standard 180 grain bullets. Distance was 13 meters, 100 rounds were fired and no malfunctions were found.

I definitely shot better using the NY1 Trigger and 3.5 lb. Connector setup. My groupings were tighter, and the difference between my left and right hands were not so obvious anymore. The smoother and lighter break of the setup was easier to shoot, though I still used slow fire (3-5 seconds between shots) method as I still didn't trust myself to shoot as well firing at a faster rate.
The trigger still feels like a two-stage trigger, but it did not affect my shooting, obviously. I guess I will be staying with this setup, and just mess around with the Striker and Striker Block Springs if I am going to lighten further that trigger break.
'Tungsten Guide Rod and Recoil'
My only complaint with this shooting session, was the recoil. I found it to sting my hands a lot more so now than in my first shooting session. I got the feeling like when you hit a solid object with a steel bar, and the bar sorts of vibrates and transfers that vibration into your hands. It felt very much like that. It got so bad that after the first 50 rounds, my hands started shaking a bit. I tried to rest it out, but the shaking took a bit of time to dissipate, and I wonder how I was still able to shoot well despite that. Thanks perhaps to the Glock's fast lock time.
