Forged can be bent...most cleveland are cast...cast can usually be bent 2* with no problem EXCEPT for the new clevelands that are made from the CCM material which I have heard is thin around the hosel and prone to cracking on even 2* tweaks, the CG 14 in particular but extending to CG 12 and CG 10s...
I have some 588s that I have bent 2*, but they aren't made of the CCM material...
I have a CG10 and a 588. I don't know if they are forged or cast, but it sounds like two degrees might be doable. (?) I don't want to invest more than about $10 per club; if it's too expensive I'll just buy something else.
You should be able to have them bent 2 degrees with no problem. Call Golfsmith to make sure, but price should be $5 to $10 each, maybe less if you have 2 done at the same time. I understand Golfsmith is making some new irons out of a different material, and they can be bent 10 degree. As has been stated, forged wedges can be bent more than cast, which would mean 3 to 4 degrees for a forged wedge. Best to ask before you break in my opinion.
I had my cast gap and sand wedge lofts bent 3° each. The guy at Golfsmith bent them 1° at a time. I suggested he heat it first, then bend them. He told me if he broke them he would replace them free.
Those P2's you have must be the irons I read about in a Goflsmith catalog. They made them out of a different alloy of stainless, one that can be bent more. I can't believe anyone would need to bend them that much, but it should mean they can be bent as much as needed without worrying about breaking them.
