Sig P320, takes Glock mags
I was just reading this blog post, about why the author thinks SOMEONE should come out with P320 frames that take Glock magazines. I have to enthusiastically say YES, if possible, that would be effin awesome sauce. If the mechanics work, then someone, somewhere, will make an absolute fortune selling these $5 polymer frames for $149.

What do you guys think?

I'm not a P320 fanboy. But if I could get an aftermarket frame (or even OEM, wink wink) that takes Glock mags, I'll buy a couple thousand worth of guns and frames.

I don't hate the idea. It irritates me that manufacturers near universally make each new model take a proprietary new magazine. I thought it was a miss not to have the 250 and later 320 take 226 and 229 mags and for the APX to not take 92 mags. I actually think it's refreshing to see the Mossberg MC1 take Glock 43 mags.

The real question is if the 320 chassis and slide stop geometry will fit the mag body.

Yeah I question whether the mag will even fit the chassis.

I can see that being a major problem. I'm fine with the grip angle on the Glocks (my beefs with the Plastic Fantastic lie elsewhere), but not everybody is. Couldn't one argue just as logically that Magpul needs to produce a Glock frame that takes some other brand of magazines? There are a lot of magazines that are "ubiquitous", and there's no real reason why some other magazine couldn't or shouldn't be as or more ubiquitous than the Glock magazine.

I sold my P320 immediately after I got it back from the "Voluntary Upgrade" along with all mags and extra grips. Lost about $175 in total...Now I see that Gen 1 P320 mags won't fit later grip modules because of the base plate?? That is messed up.
Decided Sig's would be my metal guns and Glock my Plastic guns, (My P290 is in the I don't know what to do with it catagory)
Then Glock made different Mags for Gen 5...


P220 ELITE SAO 10MM + P220 SAS GEN 2 45 ACP
P226 MK-25 9MM [2]
P227 45 ACP
M11-A1 9MM [2]
P229 SAS GEN 2 9MM + P229 SAS GEN 2 357 + P229 COMPACT SAS 357 + P229 ELITE 40 S&W
P239 SAS GEN 2 9MM + P239 SAS GEN 2 357
P290 9MM
1911 TACOPS 45ACP

Three reasons I do not care for Glocks. Grip bump, Grip Angle, & Mags that can not be easily cleaned!
Mags are part of the gun & need to be cleaned as often. Why would I want Glock mags in any gun?

Ummmm Glock mags are extremely easy to clean. I shoot a Glock at every range trip, and I dissemble the mag and clean them when I get home, every time. The key is to have a baseplate removal tool. The punch method through the floor plate sucks. Buy the magclaw tool or similar.

I honestly have no problem with a mfg. NOT using someone elses magazine. When you are designing a new firearm from scratch you limit yourself if you design it around an existing magazine. You can argue that it may be easier but it does restrict what you can do. Length, width, height, feed angle, these things may not fit into what a designer is trying to accomplish.

Now I do like when a manufacturer designes interchanability between the same family of handguns, like Glock, the M&P, the P320, etc. That makes sense to me.

When the APX came out people complained that it didn't use 92 magazines. Well the 92 magazine is completely different. The APX grip wouldn't be the APX grip if they did (I own 2 APX's and love the grip). I prefer the grip angle of an M&P over a Glock. Should Glock redesign their grip frame to take S&W magazines? Of course not. They designed it to take Glock magazines because that is what they were going for.

Imagine if the government had said that any entrant into the XM17 trials must use the M9 magazine since there are milions in inventory. The manufacturer's would have been restricted from the get go, and I guarantee that when a winner was chosen people would complain that the requirement limited their preferred vendor. Which it would have.

I see magazine compatibility as a consumer issue, i.e., it makes it cheaper for us to be able to interchange (and hoard) them. Unless a big contract calls for a specific magazine compatibility I don't think a manufacturer should care. Especially if it's not their magazine design.

People love when a rifle takes AR mags, but at least that magazine is a codeified NATO standard. Maybe if there was a NATO spec for a pistol magazine we would see more interchangability. But then we would also see limits to pistol design.

Maybe its just me, but why would I want my 320 to use a Glock mag? Especially since I don't own and never plan to own a Glock.

Now I will say this....Ruger 9mm P series mags will work in a Sig P226... you just have to cut slots in the side of the mag for it to stay in... if I could figure out how to punch a square hole in the front of the Sig mags then they would work in my Rugers too.

I embarrassed the heck out of myself trying to show a new student how to take her Glock magazines apart.

Special tool required: People would have kittens if any other manufacturer did that. But then Glock can do anything and they’re still perfect.
They should have kept the original mag design that disassembled itself if dropped on the floor.

Yes, manufacturers make money from selling magazines. That's why it's called "business."

Yep. Glock mags are unnecessarily thick.

That only applies to the X-series grip modules. And it's a 2 minute job to clip the old style baseplates so that they're compatible.

No special tool required. You can do it with only something to depress the baseplate button. The only difference is that you can't just slide the baseplate off easily like on most other mags. You have to apply extra force when sliding the baseplate to overcome the two side retaining tabs. I use the lip of a table or counter to do it.

Yes, various companies do offer special baseplate removal tools, designed to make the process easier, but they're not necessary.

Why? I mean really. Glock mags are the absolute worst. But yet some people froth all over them.

Some guys act as if cheap Glock mags are so important to them that they would only date a girl if her lady parts accepted Glock mags.

I’d jump on good less expensive mags from Magpul for Sigs.

Glock frames don't fit me at all.

And I gotta guess the grip angle will affect the feed angle of the magazine, and that's likely incompatible with the P320.

Exactly why I rid myself of all Glocks earlier this year and started buying Sigs.

IIUC, Beretta mags will fit a P226 as well; they just need different mag release cuts. Maybe this means a different "standard" already exists?

Whats wrong with Glock mags? I've ran thousands of rounds through many of them and never had an issue. Having said that, I don't recall ever having an issue with any OEM mags. Aftermarket stuff is another story, but OEM mags from major manufacturers have never given me any issues.

While I can understand why people who are heavily invested in Glock would like to be able to use their mags in everything, I don’t expect any gun to use any mags except what was designed for it.

And since I don’t own any Glock products, even if they did it, I wouldn't be a buyer. It also means I can’t visualize whether a P320 frame would have to be angled like a Glock to tske the mags. If it did, what really would be the point?
