Shotgun gunsmith in NOVA?

I just picked up an 1897 shotgun that most likely needs the chamber lengthened in order to properly fire modern 2-3/4 inch plastic shells with modern crimping. Can anyone recommend a local shop equipped to do this job? Ideally, they'd also be able to help with a front sight installation, but that's of lesser concern. thanks!

Check with Sterling Arsenal. They do work on almost everything.

Bump

Looking for a gunsmith who can very inexpensively cut down a single shot 410 from 25" to 20". Also install the front sight.

It does not need to be done perfect. If you need a shotgun to practice on, this is your chance.
