sp2022 question

[Haagenaz]

recently I bought an s2022 in 9mm and i found a site where i can buy the .40cal and .357 sig barrels and springs but i was told not to up the caliber from 9mm, any truth that I shoudnt

[m.s.g.]

There's truth in the fact that those barrels usually won't fit in the slide of your pistol. The barrels are a thicker diameter than the hole the slide. If you had a 40cal you might be able to get a conversion barrel down to a 9mm, but not the other way around.

You should have just gotten the .40 to start with. I've heard absolutely no bad bones about the .40 version 2022.
Ah, the 9 is fine. Mine's been flawless and reliable at 500 rounds plus.

Enjoy the 9!
