I picked up a 4” gp100 match champion as a dedicated magnum gun. Despite it being the fixed sight version this is what I got when looking for the same characteristics as the OP. Only around 1500 rounds with around 900 being some flavor of magnum. Mostly 125 grain cause that’s what I got a deal on. I would recommend it for this purpose. But get the adjustable sights.
I think the 4 inch makes more since for magnum than anything else. Body type matters for ccw. I can’t carry a 4 inch appendix but with wardrobe choices it’s not a problem 3 o’clock IWB. With a speeloader 1 o’clock on the belt and a speed strip in the watch pocket of certain jeans.
If it’s not a magnum gun I would much rather have some flavor of a model 10
