Just got my 357 SIG caliber x-change kit for my P250 compact. There are a lot more changes in the newer P250c's than just the grip...
1 - Grip: Some of the markings have changed positions, but nothing major. The dust-cover rail is a straight picatinny-style versus the curved style common to the SIG classics (P226). Grip shell is the same length as a P226 frame. Fits a bit loose in my Gould & Goodrich B809 holster, and a bit tight in my Bianchi IWB holster.
2 - Slide: Just heavier than the older P250 slide. Looks kind of the same, but the ejector has a beveled top corner versus a straight corner on the older model - not sure what that means. Stamping of markings is deeper on the newer slide than the older one.
3 - Recoil assembly: A big departure. The old recoil assembly was a captive-spring model with a flat spring and a plastic rod. Now it's a metal rod with a non-captive braided spring like the P229. This caused some problems (see below)...
Problems:
Okay, I mated the new kit to the old internal frame assembly (trigger/hammer group). First thing I noted was that it is extremely hard to return the takedown lever back to horizontal - I had to use a magazine edge to leverage it up. It seems to be getting better after some cycling, but at first I could barely get the slide back off!
The problem seems to be that the flange on the takedown lever shaft is supposed to fit in back of the recoil assembly - since they made the change with the assembly it seems it doesn't articulate as well as the old assembly. I think this might get better after I put a couple of hundred rounds through it, because the other part of the problem may be that the recoil spring is HEAVY! It's a blue-marked braided one, and it's probably the heaviest one they make given that it's mated to the 357 SIG barrel. Not sure if on other calibers this problem isn't as pronounced.
I will put a couple hundred through the gun and report back tomorrow.
