My trusty Ruger P90 works great, but I have one worry. The factory recoil spring is 11 lbs which seems rather weak for such a caliber. Does anybody have experience with the Wolff extra power recoil springs (such as 13Lbs) when using factory 230 grain FMJ?

Its been my experience that changing from the factory standard is a good way to turn a well functioning pistol into one that's not so good. The factory selects their spring weight to function with factory ammo, now if you load extra light or extra heavy you may find a different spring would be better but for standard factory and factory equivalent reloads you'd be better leaving things as they are.

However, Wolf springs are relatively inexpensive so if you want to try it then go ahead, buy one of their calibration packs and experiment, just save the OEM spring if the others don't work well.

The factory spring does "appear" to be weak for the pistol...same recoil spring as the 9mm P89...

One of the reserve deputies has a P90 and during qualification I noticed that his brass was really slinging out of the pistol but the pistol hadn't had but about 600 rds total thru it..anyway, I looked him up a new recoil spring from Brownell's and while I was ordering, I went ahead and got a spare spring for any of the other guys shooting a P89... they're the same spring...:scrutiny:

So, I would think that you could go up a couple of pounds without any trouble, but that's something that you just have to try before you actually know for sure. There is that point that you could get to that would actually cause accelerated wear by slamming the slide too hard going forward but by the way his pistol was throwing the brass out, I don't think a couple of more pounds on the recoil spring is gonna hurt it at all...:confused:
