What would be the cost to fly to a location within reasonable distance, pay for ammo and buy a gentleman lunch?
You 2 gentleman could agree to the following:
Buy an R9.
Both give it a test drive.
If 1 likes it and the other dislikes, then sell for cost to other.
If both like it, the other buy one too.
If both hate it, sell and I bet you will lose less than the cost of AV gas, ammo and dinner. Split the loss and call it research costs.
Good luck but do a reasonable cost benefit analysis prior to making decisions.
