Does anyone have or know where I can purchase a P320 40 Cal slide?

Hey,

These are getting harder to come by.

I was able to find one on eBay after looking for a few weeks. Gunbroker may also have a few from time to time.

Let us know how yours turns out.

Welcome to the forum!

Supply has been dried up for a while. Guys I know are buying complete pistols on Gunbroker for $275-$325 and just parting out the extra stuff.

SIG still shows them as available:

But if entire pistols can be had for that price, that would make more sense. There are numerous police trade-ins listed on Gun Broker now.

Yeah, for a slide+barrel+spring from Sig, you're looking at $280 + $180 + $70 + shipping/tax. That's over $530 just for a slide.

Even with their qualified professionals discount it's nearly as much at $460 + shipping/tax. (The slide and spring aren't discounted.)

So buying a complete .40 caliber P320 for several hundred less than that, and then parting out the grip and FCU to bring the total cost even further down, is definitely going to be the cheaper option by far.

Or, buy one in a different grip size so you can swap everything into either frame, although for that little money, just keep the one you have the way it is and get another gun!

The Sig experience center had full size P320 LE trade in pistols for $320. You could contact them about purchasing and shipping to an FFL.

Yeah buying a trade in .40 is the best bet.
