According to several sources on the internet, there are some Sig and Canik magazines that work for the Taurus PT111 G2. Is this common in the handgun world, because this is the first time I heard of something like this. Is Sig, Canik, Taurus owned by the same parent company?
 
It's not completely uncommon. There are a couple of guns that work with 3rd gen S&W mags; the model names escape me but I'm sure someone else will chime in with an answer.

Wait.... The Lion hearts work with 3rd gen mags. That's all I can remember for now.
 
Maybe the magazines are manufactured by the same vendor. I do not know who makes magazines for these companies but Mecgar makes magazines for a lot of different gun makers.
 
Most likely a fluke.

With all the similar dimensions and configurations, there are bound to be cross-overs that were never "designed" that way.
 
I don't know, if you are designing to a price point and contact Meg-Gar as a magazine OEM you could easily end up with something that matches an existing design from the catch up with the only real difference being the length below the catch and the baseplate.

Supposedly Para P14 mags work in the PT-145. They lock in and feed dummy rounds but I've never actually tried shooting them as they hang down well beyond the bottom of the grip.
 
Sometimes when a gun is being prototyped they just take an existing mag and use it with little or no alteration. Walther seems to have done this for the P5 (P38 mags) and the P88 (Beretta M92 mags). A friend reports the Hi-point 45 mags seem suspiciously like 1911 mags with a different catch cutout.
 
A lot of times the general magazine body size is the same between manufacturers - the length and floorplate, and the mag catch slot is what changes.

In those cases, if the gun you want to use the mag in has a HIGHER mag catch slot, and you don't care how the bottom of the magazine looks hanging out of the gun, then you can generally cut a new slot and use the mags.

Beretta 92 magazines are famous for being able to work in several other types of guns if you cut a new mag catch slot.
 
A 1911 magazine will work in a Kahr CW45, with just a little adjustment. CW45 come with a 6 round mag. Officer 7 round will flush fit in a Kahr CW45.
 
A friend reports the Hi-point 45 mags seem suspiciously like 1911 mags with a different catch cutout.

I remember reading on a Hi Point Forum about a guy who converted his Hi Point 45 to take stock 1911 magazines.
 
Hi Point .45 needs a bit of meat on the mag catch to work with 1911 mags. Real simple mod if you have a welder.

Kel Tec P11 works with S&W 2nd/ 3rd gen mags.
Marlin Camp Carbine 9mm works with S&W mags.
So do some of the Kel Tec Sub-2000 Gen 1.

Apparently Hi Point 9mm mags work with the Taurus 709. I'd like to get my hands on one cheap to try it out.

When Daewoo Precision Industries designed the K-5, they used the S&W M59 series magazine as a starting point for the type of magazine it would use.
This is why the K-5/DP-51/LH9 can use the S&W M59 series magazines.

All the same handgun, just different markings...
Daewoo Precision Industries K-5 (original Mil production)
Daewoo Precision Industries DP-51 (USA import version)
S&T Daewoo K-5 (S&T bought out Daewoo Precision Industries, continued production for Mil contracts)
S&T Motiv K-5 (S&T Daewoo reorganized, continued production for Mil contracts)
Lionheart Industries LH9 (USA import version made by S&T Motiv)

Many magazine designs, including that of the Sig P226, Beretta 92, Walther P99/PPQ, and Canik TP9, are based on the same cross-section. The OEM manufacturer of most of these is/was Mec-Gar, so that explains the similarity in design.

Often, all that differentiates these mags are the feed lip profile, mag release hole, length, and baseplate design.
 
Most metal double-stack mags are based off of the Browning Hi-Power mags. The angle of the grip/mag is the same, the magazine realease cut is the only thing that changes. The followers may be slightly different as well, but in general, if you change cut a new release catch, it would fit. This was done very frequently during the old AWB so that you could have new hi-caps at lower prices. Beretta 92 mags were cut and new base plates fitted for the Springfield XD, for instance.

It also makes mass-production easier. Mec-Gar makes most of the mags, so the make one tube and then alter the cuts. This explains why all of a sudden, a lot of the metal mags went from Beretta 92 smooth tube style to PX4 ribbed.
 
About 4 mos. ago the Taurus PT 111 G2 could be had off the internet for $200. I did some research and found the thing gets rave reviews. I had my local dealer order me one and I paid $225. It is not a SIG nor is it a High Point. It functions as it should without "break in" period. Size wise if I put it next to my G26 with a 15rd mag in it using an A&G grip adapter they're the same size, the Glock being a bit heavier. It's supplied with 2 12 rd mags I've got one SIG 226 Mecar 18 rd magazine. Long term, who knows. It's at least as good as some of the myriad of compact 9's on the mkt. now. Taurus engineers in Brazil probably built a laser measuring machine out of pop bottle bottoms, coconuts, and candles (like the professor on Gilligan's Island) and laser measured chambers and magazines on known working autos like SIG. Then they programmed their CNC coconut gun maker to crank them out.
