Colt 1862 pocket navy and pocket police

[jonk]

I see that these two guns both have production approvals for modern repros (Colt and Uberti specifically- at least Uberti for the Pocket Police model). However, I also note that they are available with several barrel lengths ranging from 4.5 to 6.5". The approved arms sheet doesn't specify barrel length.

So a few questions:
1. Are all barrel lengths approved, or, if not, which one(s) is/are?
2. Uberti makes a pocket navy version. Was that ruled not acceptable, or was it a case of 'no one submitted one for approval'?

Thanks!

Since cowboy shooting has taken off, imaginary weapons are appearing and selling well. Pistols with bird grips, barrel lengths that were never offered by the factory. When I first started shooting they were mostly period authentic. Thanks for your input. I am pretty sure the SAC has that information but it may not show up online.
