Glock Magazine - .40 - 31 Rounds - KCI

SKU: HKP-02297

KCI manufactured Glock 31 Round .40 Magazine

Manufactured by KCI of South Korea , Glock drop-free magazines for your Glock .40 handgun. These aftermarket Glock magazines have a hardened steel insert encased in high tech polymer (fully metal lined). This polymer coating protects the magazine and prevents deformation, even when dropped from a great height.

  • Fits all Glock .40 pistols such as the 35, 22, 23 & 27 models
  • Capacity: 31 Rounds
  • Caliber .40
  • Construction: Polymer/Steel
  • KCI manufactured and made to last

This quality replacement magazine for a Glock .40 firearm is constructed from steel and polymer just like the factory Glock mags. Each will work with all generations of Glock's including those with ambidextrous magazine releases & can be rebuilt using factory magazine parts.

Like many new magazines, these have an extremely stiff springs from the factory. It may not be possible to initially load them to full capacity. Loading half of the listed capacity and leaving it loaded overnight before the first use will ease future loadings. These mags do take some break in time to get these to work in some cases.

Please note: This item is SOLD AS IS since it is an aftermarket magazine and not a Glock factory OEM magazine and a closeout. They are priced to sell as they are no longer available and to most people are worth taking the plunge.
Condition: New

I just received my 31 round Glock magazine. I put it in my Glock 22. It looks awesome. I had to take a picture of it and send it to all my friends.

Stiff spring at first, got 13-15 rnds in right off the bat but can fill after about 2-3 days of sitting and adding a few here and there. Ive had 2, never jammed and very durable, so I bought 2 more, these really are great mags, best part is the price! Wow!

Bought one of these for my G33. Mag spring was nice and stiff. Loaded by hand. I ran Remington umc fly thru it with no problems. Fed great ran awesome even with Fast firing patterns. I'll buy more

It only fit 13 when I first got it from spring being so stiff but about 2 weeks of stretching and using speedloader I finally got 31 in. Also wish they'd put a stronger base plate on as it easily pops off if pushed wrong. But even with those problems it still functioned flawless through my glock 23. No ftf or double feeds. Really satisfied !!!
