IMO, if I was going to spend that amount of money I would go with a MOA Maximum in a better (higher pressure) cartridge.
Say like 260 Remington or 7mm-08, or even 308 Win.
They are short, lightweight hunting handguns, which are basically custom production specialty pistols.
Mine typically shoots 1/4 groups at 100 yards.
They have awesome adjustable triggers with easy to change out barrels.
You don't even need a go/no-go gauge.
He uses Douglas barrels primarily.
My best group with a 15" MOA Maximum at 1000 yards at a 1K match for 5 shots is 5.25"

I have several of them and they flat out work.
