SP2022 ROOKIE

When shooting +P and +p+ I frequently use a .40 spring which is a much heavier spring than the stock 9mm spring (20 or 22 lb vs 16 lb). I have had no issues or failures with this set up in several 1000's of +p. The heavier spring absorbs recoil, increases the dwell time the slide and barrel are locked together, and moderates slide velocity easing wear on the gun.
One of the things that I like about the SP2022 is that the gun was designed as a .40 and is a hugely robust and stoutly built design. I have no doubt that the gun will handle +p well with the stock spring, but believe the this inexpensive change will reduce wear and tear and is a good idea on a steady diet of +P.

Won't a steady diet of +P have detrimental effects on the barrel or other parts of the SP2022?

I use +P only for my self defense ammo, which I don't shoot a whole lot (at $1 a pop, I'd be crying after every trip to the range). For practice, the standard pressure ammo is just fine for my needs. But the spring thing makes sense. Doesn't SIG strongly recommend NOT to use +p+ in their guns? I think I read something like that, somewhere.

+P+ is hot stuff no SAAMI specifications for it. No manufacturer would want to accept the liability for its use.....
One of the things I Like about SP2022 series is that they are built like a tank. They have a generous lockup of the barrel, great support of the barrel cam, steel slide rails. They were designed as a 40 which is far more stressful than 9mm. Even shooting large doses of +p I am of the opinion that lifespan on these should be extremely high.
I have been playing with reloading a large batch of +p 124 jhp for a local monthly pin shoot.
