You can get a 320 or 365 that way among others. I'm sure you can also do it with aftermarket triggers on others.By "NICE", do you mean no dingle or just a better feel & break?
I might try a striker pistol if there was one without the stupid bifurcated trigger and had a manual safety.
P10F 45acp is made in Czech. I was told by CZ USA that they rarely get over here. So if you see one maybe grab it and ask a barrel company to make a threaded barrel for it.I’ve looked high and low for the CZ P10-F can’t seem to find the threaded barrel or model with the threaded barrel in 45acp…. I see the 9mm variant everywhere.
I might try a striker pistol if there was one without the stupid trigger that has a mile long takeup.
