I want to grab one of the new pro cut slides, a certain grip frame and a threaded barrel. In order to get there, is it easier to get a complete pistol and keep the FCU and parts I want, selling the rest off? Or better to get a FCU and then put it together?

I have the idea in my head of what I want but I haven't kept up on all the different variations and compatability.

I basically want a full size grip, compact slide, threaded barrel with tall sights and an RDS for a suppressor host. The X-Carry looks close.

You can accomplish this a number of ways. You can start with an FCU or a gun. "Best way" really depends on if you want to emphasize ease/speed to acquire and convert, or if you're trying to minimize cost.

You're looking for a carry configuration, for sure. 17rd grip and compact slide is the Carry setup.

The M18 is also close, it's an optics-ready carry configuration with a safety.

The X-carry is probably the best starting spot. You'd just need a threaded barrel and RomeoPro or DeltaPointPro. It cannot, however, have a traditional set of suppressor height sights added. You'd need to use the optic rear sight that either sight has, and swap out the front post for some other height to get cowitness irons. I don't know what that height needs to be.

Now, is it more advantageous to start with the X-carry, trade for a different slide and keep the upgraded FCU? Maybe, if the cost works out, the trade works out, and you want that setup. But that could be true of just about any starting P320.

Getting a bone stock, cheap as dirt P320 plus custom work for the optics cut, suppressor sights, and a threaded barrel (plus any trigger upgrades you want) is also an option.

You could also get an 80% FCU and build the gun from scratch.

You can also get a full size grip module, like the new Wilson one, and chop the end off to make it a carry size.

Otherwise, you just need to match post-upgrade with like parts; can't mix a pre-upgrade FCU with a post-upgrade slide.

Is the FCU of the X5 just a P320 FCU with no modifications? Can you buy just an FCU of any of these pistols?

I recently did what you are looking to do but I went with the Xcompact sized grip instead of the Xcarry size grip. But everything else sounds like our builds will be similar.

I started with a complete FCU from a donor gun. I sold the parts I did not want to recoup some of the cost of the build.

The only difference that I can tell between a standard P320, X5, and Legion is the trigger. And the order is best trigger pull is P320<X5<Legion. But the internals of the FCU are identical. But if you go with a Grayguns competition kit it is the best and it does not matter what FCU you start with.

Here is a picture of my build.

Thanks. I guess I need to run some numbers and see what the X-Carry slide, barrel and grip module would sell for. I found a FCU by itself for $270. It's the cost of all the small parts I might need that keeps me looking at a complete gun to start.

If I ordered a slide, barrel and grip module...I'd need to get mags (prices vary but at least x2 to match a complete gun price), take-down lever ($20 or so), recoil assembly ($50). Anything else? It's been a few years since I sold my P320's and 250's.

I would reccomend picking up a complete gun for the reason of magazines, small parts, ect. At $270 for just the FCU, you are half the way to a complete Xcarry.

There is always someone willing to buy your unused parts for a project they are working on.

The X-Carry slide isn't compatible with any threaded bbl. FYI, I have a brand new compact pro cut slide, tac-ops bbl, recoil assembly and X-Carry frame FS. Even have an Apex Trigger Kit. All brand new. Email me if interested. I'm going to list here soon. It's a complete gun sans FCU and Mags. Seems to be exactly what you're looking for.

Can you elaborate a little bit more on the XCarry slide not being able to use a threaded barrel? I do not have an Xcarry but the slide length is the same size as a carry/compact slide so I always figured that it could use a threaded barrel meant for a carry/compact size.

The bbl on the X-Carry is compatible with the X-Carry only. The lock-up is different than that of the non X line. Therefore you CAN NOT use a compact bbl in the X-Carry. Threaded or not.

is that a function of the X-line or the Compact vs. Carry? I see there's an X-Compact as well and the slide I want it is the Compact Pro one since they don't make a Carry Pro in stainless.

I'd only use the lower half of the X-Carry and would put a Compact pro slide and Compact threaded barrel on it.

Yes the compact pro cut slide and a compact threaded barrel work together. That is the combination that I am using on the gun I posted a picture of.

+1. I just did what you are discussing and spent $260 on a X5 FCU, and $275 on a XChange kit plus $13 on a takedown lever.

If I'd had seen this earlier, I just would have bought the whole gun P320 Compact for $420 and added a GG trigger.

yes, but my question was compatability around the pro slide and the X-Compact barrel vs. normal threaded compact barrel in the X-slide.

This is about to get confusing but I will try and help.

The X-compact has the same size slide as a standard sub compact P320 (3.6 inches)

A compact, carry and pro cut compact slide is the same size (3.9 inches)

The pro cut slide will take any barrel that is made for that size of P320. There are 3 sizes, sub compact, Compact, and full size. Just pick your slide and then pick your barrel. The factory only offers one size that is threaded and it is the compact size.

That is correct!

P320 Subcompact = X-Compact (Slide)
P320 Compact = X-Carry (Slide length)


I don't know if a P320 subcompact bbl (threaded or not) is compatible with X-Compact.

I can confirm the P320 Compact bbl (threaded or not, factory or not) is NOT comparable with X-Carry. The X-Carry has a unique bbl. Lockup is different.

If you want a threaded bbl AND mount a DP pro or RM1 Pro, it will have to be the Pro-Cut slide. Also, rear site remains as it isn't mounted to cover plate like in X-Carry.

Interesting: I no longer see the Compact Pro-Cut slide in stainless. Black and FDE in three sizes. But only Full and subcompact in stainless.

Like I said I have a Pro-Cut compact in stainless.

Yep...I started out thinking about this because the Compact slide in stainless.

Email me if you'd like to talk. I'll be posting in Classifieds the above listed components. But if you're interested, maybe we can work something out. No pressure.
