DOJ Roster question

[RP1911]

Some of the Springfield pistols are listed with L at the end. As an example: PxxxxxL.

However, I have found one where the box says PxxxxxLP.

What does the P stand for and will that make it non-transferrable (unless PPT obviously)?

P - Package. Like case and holster and extra mag and etc.

If the other characters are the same, you can ignore that.

Thanks.
