Really wanted to test out the 4” slide + TR barrel combo and decided to sneak in some range time on game day, well, all lanes were open except for 2, so I was able to at least function test the 4” setup. Brought 2 boxes circa Y2K – 1x Geco 124 Gr Ball & 1xAmerican Eagle 147Gr FMJFP, kid at the counter said “these are old”, my response – “as long as they go boom when I pull".
I was shooting with S&W night sights from CDNN (TG green on green), I eyeballed the rear when it was pushed in, about dead center, bought a laser bore sighter from Amazon afterward and it said I was lined up in windage but low on elevation, not much I could do save for tweaking the front.
The bullets landed about where the sights indicated, a hair low @ 25’ – 30’ but windage is good. I went back to my habit of using the slide stop as a release, with the proper S&W recoil spring, I had no trouble, I didn’t have to pull the slide back to feed. OTOH, with the 1.0 Shield setup, it was tough to do the same.
1st 50 rounds were the Geco, not a single feed issue, OTOH, the Federals gave me 4-5 FTF’s, which has to do with the factory 8-round mags, when these are filled with 7 rounds, not a single hiccup.
I did have to clean the new TR (Remsport) barrel a bit before range, but it wasn’t terrible by any stretch to get it ready. I am happy with the 4” combo, shoots smoothly, and I now have options. You see, the bar is so low here on the left coast, I am easy to please... LOL.
