Where can a guy buy just the replacement grip, not the entire kit? Want some for a P229. I'll check with Sig, didn't want to pay $40 though.

They show up from time to time here and on other auction sites for a decent price. If and when you decide to put them on, check on the site here or youtube on how to install using the credit card trick. The reason is the trigger spring can be bent/destroyed when putting the E2 grips on if you are not careful. I screwed up a couple springs prior to using the technique. It will save you some headaches.

Hey, good idea! I have them on my P229, but wanted a set for my new M11-A1. Yeah, definitely need to be careful on the springs. I found a new set on ebay for my P227 for $17 shipped, didn't get that lucky on this gun.
