I know in your original post you kind of discounted an LTT Px4 Compact Carry. Reason being is that it is limited support with the primary reason of that it is a mostly solely supported platform by LTT. True, but it is COMPLETELY supported by LTT and I don't think LTT or Ernest are going away anytime soon. I've been toting around and shooting a self Langdonized PX4 CC for almost 5 years now. It is the easiest pistol for me to shoot accurately quickly. Since I've added a PX4 slide with a Holo 507C to the mix with the LTT RDS Solution Gen 2 things have improved significantly. The big secret on the PX4 CC is that the dimensions aren't G19 sized. They are more G43X sized. Check out this link, find my post and see the comparison. It is also super comfy, all day long, riding in a Black Rhino Concealment AIWB with a TLR7. It looks like the TRL7A will fit this pistol with one of the supplied keys.

The choice is all yours but I think you might truly miss out if you discount a Langdonized PX4 CC right from the start.
