I've owned P Series pistols since 1990 and have learned a little about them over the years. I picked up an LC9s since they legalized constitutional carry in my section of flyover country. I was running a search to find the serial number page for the .40S&W P94 (which I still can't find) and found a thread on this forum about magazine fit between early and late P89, that needs a little help, so I'll throw in my two cents on that.

They had the list pages indexed somewhere, and they got rid of the index. I bookmarked the 9mm pages, but I am trying to figure out if the serial number for the 94 has a digit to indicate the difference between 9mm and .40S&W. It's the same sequence for manual and decocker for the 9mm. I'd like to figure out if the build notes have a difference. I'm converting frames over to decocker, and I picked up one with bad sear engagement that doesn't want to drop the hammer with the safety or decocker. Factory always converts back to factory spec and I can't afford to lose a decocker slide if I send it in for a bad sear.

Forgot the links:

There should be something like "PI-P944D" and "PI-P944".

.40S&W serial numbers start with "340-" and "341-". Definitely not gonna get away with converting a .40S&W over to 9mm and shipping it back for factory service.

This may be a good topic and get more info out if you start a thread in the Semi Auto Section too.
