This past Friday (1 APR 16) I picked up a 930 JM Pro for 3 Gun. After shooting it the next day I identified some weakness regarding running the gun smoothly for 3 Gun.
The loading port needs to enlarged for quad loads or doubles, the rear of the forearm needs to be shaved, a larger bolt release, and the lifter needs to be changed or welded to avoid pinching the thumb. I will also be modding the trigger as well. I've found a few websites for parts and I figured I would list them incase others want to do the same. I will be doing the loading port and forearm myself so I really can't help you there, cause at this time I'm not looking to mod a ton of them, unless I can do it cleanly and easily. I am on the fence about a side saddle and will prob end up going with an elastic one that velcros to the receiver.
