357 sig original barrel - SIG SAUER P229 Barrel, .357SIG, Blued

I own a Sig P229R Equinox in 40cal/357 SIG and decided to switch to 357 Sig mode. The difference was quite noticeable when shooting 125 gr hot loads from two different reputable manufacturers, one rated at 1475 FPS and the other one at 1545 FPS. If you shoot a lot, I recommend you get an extra barrel to have it handy in case you notice shooting patterns that could be associated with barrel wear. The same goes for recoil springs. I switched to a 21 lbs spring. So far I haven't noticed anything that may indicate a need to use either the spare barrel or the spare recoil spring, but it is good to know that you have spare ones in case you need them.
