The 1909 is a great action and I have built many rifles on this action with no problem. However converting any military action involves lots of work and that means expense. True if done right you can end up with a true one of a kind custom job but it will cost you. If you want to go with a military action and go this way look at the P-14, P-17 actions, they are big strong and when re worked right look like a 720 Remington.
