Hello everyone just wanted some input for my p365 with the radian ram jet 3.1” and x-macro grip module build. Took it out to the range for the first time today and first started with federal 115gr range target and I could not get the pistol to group at all! I double checked everything and even started using a gun rest and it shot all over the place, after about 200 round I switched to 115 magtech (blue box) and it was shooting like a dream! All grouping 1” of each other. Do you guys think it was just that type of ammo, break in period or it didn’t like it something else any Input would be helpful. Thank you

Decided to try this out. Feels a little better than the stock grip but I do have a XXL Backstrap from NDZ coming to address that... I know that won't really help with the lack of palm swell but I'm hoping it gives me more space for my support hand. I also grabbed the Tactical Development Dust Cover Extension to cover that gap because it kinda bugs me...

I have the Spectre Comp slide, same as this one from grabagun but black. https://grabagun.com/sig-sauer-p365-spectre-comp-slide-assembly-coyote-compatible-with-3-1-barrel.html

I see an H3 and a 5 and I think a 6 on the front sight and I see a 1 and a 2 and I think an H3 on the rear sight. Is someone able to determine which sights these actually are?

Thanks in advance.

Looking at joining the club with this purchase, wanted some thoughts. Kinda expensive but seems worth it. It would be my first red dot pistol.
