Lawman:
Welcome to the Forum, and judging from your "handle," I thank you for your service in law enforcement.
The recoil springs of the R9 have a lot of work to do to handle a full-house 9mm Parabellum cartridge in a 13-ounce work of art. The springs cost $4.99 each, which is about the cost of five rounds of top-line 9mm ammunition these days. I'm obsessive-compulsive about the early Farmingdale R9 that has been my EDC since May 2004 and I have adhered to the mantra of changing recoil springs after each 200 rounds or so. That little masterpiece still looks rather good and is my pocket as I type this post:
