I did read that about factory ammo, a lot of it is watered down. I was looking at underwood or some Hornady ammo. How was the g40? I heard that the recoil isn’t too bad in the g40.
The G40 handles the recoil well, max loads are stout for sure but manageable. I was able to lay 10 rounds in a good group pretty fast. Its not uncomfortable to shoot imo. I think you will be very happy with your G40. I think the Sig factory is not to watered down for range type stuff. I will ask my buddy, since he has tried several types and report back.
