Cutting the springs reduces the force of the electors and probably helps life. It is also easy to undo, just buy new springs. Cutting the ejectors is a more permanent option. Once they are cut the only way to undo it is to have a smith install new ejectors.
I have cut the springs on my guns and with a thumb over the shells they stay put.
I prefer extractors but on my 2 Beretta 687's I just catch the empties as they are ejected.
If you must mess with it just shorten the springs.
If you mess with the actual ejectors to convert them to extractor it is not reversible. If you then wish to convert the gun back to ejector you must buy 2 ejectors, have them fitted, finished and then heat treated - Rich Cole's website prices for the 2 ejectors, 2 springs, fitting, finishing and heat treating is $372. A knowledgeable buyer would knock about $500 - $600 off of your resale price for the cost to make it an ejector gun again and the inconvenience of having to do so.
Actually, it does not involve modifying the ejectors- it requires changing the profiles on the forearm levers. I believe Coles does this, I think someone posted that they charge $50 for the service. To go back to ejectors you have to replace the modified forearm levers.
The ejectors are an expensive proposition - don't mess with them unless you know what you are doing.
