I shot a 930 for a couple of years in local 3 gun and is was extremely reliable, until it wasn't. Started having random light strikes and it would fail to pick up a shell (repeatedly) I was told (by someone I trust) that I needed a new, heavier hammer spring. I bough one and after getting to the point where I was ready to install it, I realized that I'd need three hands and was a great risk of shooting it across the room to never be seen again. I also realized that even if I got it right (eventually) I was going to have to probably do it all again in a year or two. I put it back together and sold it and bought a 1301 on recommendations from fellow 3 gun shooters. I had looked at the 940, but I couldn't confirm that that had done anything about the hammer spring. Also, the 940 and 930 have the lifter down and is has to be "pushed" out of the way by the shell when reloading. The 1301 Comp Pro (blue receiver) has it up and out of the way. Also, when you pick up a 930 or 940 and then a 1301 and hand cycle them, the clear winner is the 1301. It pains me to say that as a Hillbilly American, who loves to buy American. When I bought my 1301, the Savage Reneguage wasn't out yet. You may want to take a look at that one as well if you can find one in a store. I've been looking for months and have only see field guns. No tactical or 3 gun models. Can't really go wrong with the M4 except for the price and the fact that it takes @another $200 to get it up to "regular" capacity. Shoot a 1301 before you decide.
