I sent off a Glock slide off to JagerWerks a little over 7 weeks ago to be milled and nitrided. While it was away i saw the nitride time increased from 1-2 weeks to 3-4. No big deal, there's a lot going on in the world right now.

Anyone sent off a slide since early April and already gotten it back?

Though I've used them on at least 3 occasions in the past, I have not sent anything there in the last year.  That said, their work is literally perfect, and they're usually pretty accurate with expected lead times in my experience.  

They're also pretty active on Instagram if you decide to follow them.  They are absolutely buried right now - they've commented on it being the busiest it has ever been at a time of year that is usually much less so.  

Try to tough it out - the work is worth the wait.

Edit 8/7: Apologies - didn't notice how old your OP was.

It depends if you want the slide refinished. That takes longer because they farm that out to TechNickel in Benton Harbor, MI. I've had three slides milled and refinished by them and am 100% satisfied with the outcome.
