How do you know when the recoil spring in Beretta autos needs changing? What problems start to show up? indicating it is time to change the spring? I have heard compare the length of the old spring to a new one,but would think something in how the gun functions should tell you.My 390 has been shot alot,I didnot keep track of how many rounds,the gun still functions reliably. When do I know its time to change the recoil spring? Thanks for any help. Paul

I change mine on the 303's once a year but I shoot some really fast heavy loads. They have a habit of damaging the ( usually bolt first but reciever sometimes)when the spring gets weak and you continously shoot big loads. I order magnum springs from Cole or MGW

Paul,

How far is your 390 throwing the empty hulls? If it's 6 feet or less, the spring is probably still good. If it's closer to 9 or 10 feet, then it's time to replace the spring..... NOW.

My first 391, I went every bit of 100,000 with the original spring and replaced it just as a maintenance concern. If you start breaking buffers, that could be a cue, otherwise I would say you could go at least 50,000 without being too concerned.

The Sporting Clays group that I shoot with have all abused their 391's and have gone year after year and many thousands of rounds without doing anything but an occasional (and I do mean occasional) cleaning.

The length of the old vs. the new recoil spring will tell you nothing, as they would appear to be identical in length, or the replacement may even be a little shorter.

390 to 391 is apples to oranges as far as the action springs go. The 390 has NO buffer, either in the receiver or bolt. If the spring gets worn, the rear bolt face slams into the alloy receiver and sump'ns gotta give!! Replace it at least every 10,000 rounds. It's a cheap, 10 minute job.
