Hi, I just got a new P320 carry , I was able to take it apart fine but have a difficult time putting it back together.
The slide will only go half way in and it seems something is preventing it from going all the way in. I followed the instruction manual and the take down lever is where it should be.
Any suggestions?
Thank you

Check the guide rod orientation. The breech end may have flats on two sides. These flats need to be up and down, that is, at at 90 degree angle to the bore.

There is something else to check as well. I can’t quite remember what it is though. Lol. Something to do with the magazine takedown safety. Somebody help me out here.

If you pushed the slide release levers up prior to reassembling, it resets the mag safety. To reactivity the mag safety, turn the takedown lever horizontal (normal position) then back to the takedown position.

I seem to recall early P320 guide rods having specific orientation requirements but you said it's new. If it's just new to you, or old stock, check your manual on that.

It's also possible you just need to apply a little downward pressure on the slide to get it to line up on the rails right.

ETA: just saw you're in the Philippines. I dunno how often you get current models, so I wouldn't be surprised if it's old stock.

I could be wrong, but I thought the guide-rod orientation issue was only with Subcompacts.

Put all the pieces in a non-transparent bag, preferably with soft material. A crown royal bag works well. Close the bag, loop once with cord, and shake.

The pistol will assemble itself. Verify correct assembly.

How'd you make out? I assume you didn't have to resort to the "magic bag"

If you are still having trouble, try a YouTube video. Sometimes that helps.

Is the sear sticking up? Any pressure on the trigger can do this.

HI, thanks for all the inputs . The manual says there is a guide rod orientation- the flat sides should all be vertical but the flat sides on the guide rod ends are in the front of the guide rod (the side that is just under the muzzel). The back of the guide rod is round- this is the part that mates with the end of the barrel. I aligned the front with the flat sides up but still have a problem.
We have an official sig dealer here in the Philippine so I assume the stocks they have are current .

I just tried all kinda of different ways to make the slide hang up, and couldn't do it. The only thing that might be possible is you don't have the takedown lever pushed through all the way.

Or you're just hitting the resistance of the safety lever and disconnector and aren't pushing through it. But you said only halfway on, which is basically where it starts. You didn't have multiple pistols apart and mixed up barrels?

Maybe if you could snap a few pictures and post?

Did you pull the trigger housing out? It's easy enough not to seat it properly in the grip frame if you've never done it before.

Or, if you pulled out the takedown lever, you need to rotate/wiggle it as you push to get it to fully seat.

Push up on the slide release, this releases the take down lever so you can rotate the lever downward again. If you have pulled the trigger with the slide off, then there this little "finger" that got push up on the back of the frame, you have to push it back down or else the slide would not make it pass the last 1/4 of travel.

I think you might have the recoil/guide rod assembly installed backwards. The round end goes toward the muzzle. In this video, at around 30 seconds you'll see the slide removed and the guide rod assembly still in place:

Wow, everything looks soooo easy in the video. I noticed the recoil spring assembly in mine has the ends with flat edges in the front side- where it goes into the frame- some mixup in the factory?

No mixup. There are 2 kinds of recoil spring assemblies. This is a picture of one where the flats matter:


If yours is circular where this one is rectangular, it doesn't matter how you orient it. And the other end will have flats, and that's the muzzle end.

Really, take some pictures, use a photo sharing site (I use postimg.cc) and post the pics.

Take pictures of what the FCU unit looks like in the frame, what the slide with barrel and recoil assembly looks like, and how far you get the slide on the frame.

The carry configuration the OP has is the compact slide/barrel on a frame that has the full size length grip. The subcompact has a shorter slide/barrel, so it may not have the same recoil spring and guide as the compact/carry. On my P320, which started out as a compact, but I converted to a carry with the full sized frame, the muzzle end of the guide rod has the two flats, while the breach end of the guide rod, which rests against the barrel lug is round. The muzzle end of the recoil spring assembly is always the “fat” part of the two spring design, no matter what size the pistol, or whether the muzzle end of the guide rod is round or has the two flats. On mine, because the rear guide rod goes against the barrel lug is round, the position of the flats at the muzzle has no bearing on whether it goes back together or not.

Many thanks for all the inputs. Got to put it back together. I am happy and thankful for all the support.

You can't do us like that! What ended up being the solution?

From what you guys said, I found out that the takedown lever was not fully rotated- this allowed the slide to go past the half way mark, also some parts were sticking out at the end- the safety lever or disconector as one person pointed out, I encountered some resistance here in pushing the slide all the way, I pushed the slide past this and all got to assemble the slie. I am grateful for all the inputs. I have a P226 and never had a problem like this. thank you again
