I retract my story and comments. Just wanted to let people know of an issue I found out.
Let me just quote Pappabear from below:
"The 320 is a great gun, but if you fck with it, do so at your own peril because it’s not quite as plug and play as Sig might suggest."
Have a great day

Ha ha ha. So just to be clear, you bought a grip module with a cutout for a safety and dropped in a fcu without a safety, Sig advises not to do so, it doesn’t work out well, and you are pissed at Sig. About cover it?

Dang dude. Have you ever looked at the fcu? It is a microcosm of tiny parts, pins and spring that yes, are held in place partly by the confines of the grip module.

It not working out well should not shock you. It certainly shouldn’t make you post a thread that most gun guys are going to say……, “what did you think would happen?” or “why did you buy the wrong grip module?”

Good news is that Sig will do just fine being short one “advocate”. Lol

Sorry you've had a bad experience but these experiences don't sound like design flaws.

And why are these type posts starting to read like online recipes?

There is always a backstory now..."My first memory of Sig was when my Grandma cooked dinner every Sunday..."

Grandma did love her striker fired guns.As I slowly wipe a tear from my cheek..

Not sure how to help you with that one...maybe pay attention when you take stuff apart so you don't lose parts?

I have a couple of FCUs with a lot of rounds through them. They have some loose pins. I just pay attention when I pull the FCU to make sure they don't fall out, make sure they're still there and properly seated when I put it back in the grip module, and function test before I load up to put it back in the holster. I clean my guns every time I shoot them, and as a result have one apart at least every week or so...it hasn't been a hardship for me.

Once again, I am reminding members that when posting in threads such as this, it's important to take into account the frustration of the OP.

If it comes to a point where the gloves are off, you'll know it. Until then- manners, manners, manners.

Let me understand that a pistol designed to move the FCU from one grip to another has a known issue of the trigger pin falling out??????

Manufacturing issue or modularity issue aside, the dude has a point. Sig has made its bones telling us how swappable the 320 line-up is. And it is, but sometimes...

Of course there is zero cool factor in telling your customers that sometimes when you're swapping thing A to thing B, shit's gonna fall off, and then your gun won't work.

For the record, I've had several 320s and have nothing against them.

I hope the OP doesn't get a Ruger 10/22. While it is a great shooter, taking it apart for cleaning does have a lot pins that like to pop out if you are not careful...

Agreed.

Not ever having experienced swapping my P320's FCU around, I was not aware of this issue. Now I am. But, I have to agree with the OP: A pistol that is touted to be modular, allegedly designed to swap bits around to re-configure, ought to be designed such that small bits don't tend wander away when you do that.

Does Ruger make a big selling point out of how swappable the 10/22 internals are? If they did, I'd agree with you - and the same goes for the 228. The point is, Sig bragged about how interchangeable this pistol, in particular, is. But they don't expend much - if any - effort telling you that it may come unmanufactured when you do that.

I've swapped several FCUs and never had it happen, but the potential is there.

I have multiple FCU's and have swapped them to different grip modules dozens of times and have never had an issue, ever.

This

I think everyone has made good points on this thread. And I too have multiple 320’s and my X5 is one of my favs. But newbies should all read this thread because it is filled with good advice and I think it goes like this.

The 320 is a great gun, but if you fck with it, do so at your own peril because it’s not quite as plug and play as Sig might suggest.

Sounds right to me

I hear the OPs frustration but I've not experienced this problem with my Wilson grip on a 5" 9mm.

When you incorporate factory and aftermarket parts there's always ifitting needed, including SIG.

From an engineering viewpoint, the 320 is designed for thier stacked tolerances.

I've watched 320s since inception. I haven't seen them tout interchangability with aftermarket parts.

I will agree the 320 has some fiddly parts, and yes some of the trigger pins are loose and can fall out.

With that, aside from the modularity of the 320, you still need to pay attention when changing parts, and FCU's from one frame to another. This is something that should be done when taking any firearm, or any item apart for that matter.

Just because the 320 is modular, doesn't mean you can just take it apart all willy nilly.
If that trigger pin got you confabulated, I would hate to have seen you remove the striker assembly from one.

Nothing wrong with moving on the CR platform, but to shun a particular product over your inability to monitor parts while you were servicing your 320, is just silly.


TXPO

An fyi, some have had issues with removing the 365 fcu and having shit go wrong.

Not slamming the 365, I like it, but the potential is there.

I like bacon cheeseburgers, fries and cold beer! If I put a fried egg on my bacon cheeseburger, sometimes the yoke runs. I sop it up with fries and wash it down with beer. I don't blame the runny yoke.

As was the P250, similar concept, albeit hammer fired, you could mess up the FCU and make the gun not run moving it from one frame to another.

Advice is, look to you tube for videos on how to disassemble, clean, reassemble any firearm, plenty of videos out there.

It's with anything mechanical that's not inherently flawed. If you're not mechanically inclined, you're going to mess up somewhere along the way. If you're not familiar with it and just dive into it, same will happen. Give me the classic P-series SIG, and I'll work with it in my sleep. But, give me the P320, and I'll surely eff it up somehow.
