I have been slowly collecting all the parts to put together a p365 slide.

My eyes are not what they used to be.

I was going to put it together but I am thinking of taking it to a gunsmith for assembly.

What would be a fair price for that?

It includes putting in TruGlow sights and installing a Romeo Zero to a pre-cut slide.

Does anyone know of a good gunsmith in the Boston to southern NH area?

Honestly, what you are looking to do is fairly straightforward and can be accomplish with basic home tools. I say you watch a Youtube video and you'll be done with your project in less time than it will take you to drive to the gunsmith and back

^^^ That.

Very easy operation and only requires watching a video tutorial. Not worth the time, let alone the money, a gunsmith will charge.

If you did not want to do this yourself, contact the SIG Sauer Pro Shop at the Academy and see if they can help you. They are right in southern New Hampshire.

I was going to do that but I have a third party slide.

All the other parts are new from Sig directly.

Shouldn't take a qualified Sig Smith more than 45 minutes for the job with sights consuming the most time. I could do it sans the sights in 20 minutes. Maybe the third party slide company offers such service, if not let your fingers do the walking and call a few respected Smiths.
