Will a Glock 22 mag fit and function inside a glock 17? Just got an e-mail from CSSA saying many mags designed for .40 S&W will fit and function in a 9mm model from the same manufacturer - if so, anyone know if it works for a Glock 22 to 17?
 
From the CSSA

Did you know?

Many .40 S&W handgun mags are perfectly usable in 9mm Luger pistols. These magazines will hold an extra 3-4 shots. For example, the Beretta 96 .40 S&W magazine will hold 14 rounds of 9mm ammunition and functions perfectly in Beretta 92 pistols and Cx4 carbines. Not only is the extra magazine capacity handy, IT IS PERFECTLY LEGAL!

In a letter dated July 9, 2007, RCMP Senior Firearms Technologist William Etter states, "The Former Cartridge Magazine Control Regulations are oriented to the possession of Cartridge Magazines. Once a cartridge magazine is acceptable as a magazine for a "handgun, commonly available in Canada" and is capable of containing ten shots or less of the kind or type for which the magazine was originally designed, its further use in any other handgun or any other calibre cartridge is not regulated.

The use of a Heckler & P7 M10 cartridge magazine in a Heckler & P7 M13 firearm loaded with 13 cartridges of 9MM LUGER calibre, in our opinion, would not constitute a violation of the Former Cartridge Magazine Control Regulations."

This is great news for pistol shooters. Canadian shooters have envied our American cousins since the onset of our silly magazine restrictions came into force. Now it appears, there is a little light at the end of the tunnel.

Wish I knew about that before buying 7 10 round Glock 17 mags.
 
Thinking about the basic physics of this - if you load a 22 mag to capacity with 9mm, it puts a major stress on the feed lips, which could cause them to warp, which, with the smaller 9mm casing, might case the rounds to come flying out. I'm thinking - if you cut the mag spring, you should ease the tension on the feed lips, prevent them from warping, and you don't have a problem - that's the real dilemma I'm pondering.

Now another related question - what's the best way to cut a mag spring - those buggers are tough and your average cable cutter isn't really up to the task.

Cutting the mag spring will result in the magazine becoming a prohibited device.

Also, if you're intending on using .40 mags in a glock 17 and loading past 10 rounds, be sure the mags are stamped .40, otherwise its tough to prove that its manufactured with a 10 round limit (based on the gun it was designed for, the G22)
 
I sure did - and seeing as it's established that it's legal to do so - does it work well with this specific combination - Glock 22 - 17?

I missed that one too! What a revelation - LOL! I had no clue you could do that, but it makes perfect sense. Cutting the spring shouldn't make a "hill of beans" difference, as long as .40S&W mag's capacity remains limited to 10 rounds of .40S&W.

Sigh - and why exactly would that be the case? If you snip off a small section of the spring such that it still only holds 10x .40 S&W rounds - how does that make it a prohibited device?

its the wording in the CC regs.

Once you cut springs, you can no longer argue that the magazine was originally designed for the G22, in fact, by cutting springs you are altering the mag to work in G17....and since it can hold beyond 10 rounds, it would become a prohibited device.
 
You're assuming someone would cut the springs to adapt it to shoot in a Glock 17 and not to make it easier to load that 10th round of .40 S&W into their mag.

Where in the CC is the exact section related to altering a magazine turns it into a prohibited device?

PART 4

(ii) a semi-automatic firearm other than a semi-automatic handgun,
(iii) an automatic firearm whether or not it has been altered to discharge only one projectile with one pressure of the trigger,
(iv) the firearms of the designs commonly known as the Ingram M10 and M11 pistols, and any variants or modified versions of them, including the Cobray M10 and M11 pistols, the RPB M10, M11 and SM11 pistols and the SWD M10, M11, SM10 and SM11 pistols,

"containing more than 10 cartridges of the type for which the magazine was originally designed" - cutting the spring slightly does nothing that violate that condition.
