1911 firing pin stop question

[SavageMOA]

I've searched everywhere and cannot find an answer.

I'm putting together a .40S&W 1911. I'm going to use a series 70 configuration. Do I have to have a caliber specific firing pin stop? Or will one like this work?

From what I can gather it looks like there are specific firing pins/stops for specific calibers. Unfortunately I don't see .40 mentioned in my limited travels though. If it was me, I would just give those guys at Brownells a call and ask them what they think.

There are Series 80 firing pin stops, and non-Series 80 stops, but among centerfire calibers, they are not caliber-specific. The tip of the firing pin will vary with caliber, but the back end is the same.

That's what I figured, just wanted to be sure though.

Thanks fellas!
