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 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 Korean magazine and not a Glock factory OEM magazine. They are priced to sell no longer available and to most people are worth taking the plunge.

"Really good mag for a really good price."

Patrick Deshazo on 2/16/2014 2:37:52 PM

Comments and Suggestions: Love this mag, haven't had any problems with the chambering of rounds, love how there's a grip on the mag itself for steadier aiming. Only reason it isn't 5 stars is that the 2nd round sounds loose in the mag when you shake it. Hasn't been a problem, YET. But we'll see with the more rounds I put through it...


"high cap mag"

Comments and Suggestions: 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

Comments and Suggestions: I have not had the chance to run any rounds through the mag yet, but i was surprised that i could actually get it loaded by hand! Solid mag, will definitely be buying from HK Parts again, shipping was really fast and i even got a smiley face on my packing slip!

Comments and Suggestions: I ordered 6 mads not really knowing what to expect but upon receiving the items I have to say that they looked very well made and when I went to load them up the springs were really tight that's a good sign I'm still waiting to go shoot but to all of those looking to buy these mags are skeptical because they're Korean well they're worth every penny as a matter of fact I might be ordering more.


"Perfect function for half price"

Comments and Suggestions: Highly recommend the KCI mags. They work exactly as OEM Glock and we're available. I have found virtually no difference in appearance, form & function of these mags. No failures of any kind through about 500 rounds of plate shooting.

"Works Well with Quality Ammo"

Dave K. on 10/8/2013 4:42:56 PM

Comments and Suggestions: I bought these to use with my Kel Tec Sub 2000 (.40 S&W). I was disappointed at first because I got a lot of Failure to Eject malfunctions with them and I wouldn't get any FTE's with the 10 round OEM magazine. That was with cheap, remanufactured ammo though. I've since run Wichester White Box and Federal Champion ammo throught the KCI magazines without any problems. I would be willing to buy more of them (especially from HK Parts) now that I know they run well when you use decent quality ammo an... More details

Comments and Suggestions: Good Mags just be sure to use graphite. I purchased 8 mags. Graphite makes these mags 100% reliable

Comments and Suggestions: This is the only place I have been able to find these magazines, I am thankful. The springs are stiff and the ammo does hang up using these mags. Dry Graphite will be necessary for proper feeding. Dry graphite will not hurt ammo or gun. Just dont use to much. I have 10 of these mags with the use of Dry Graphite these mags are 100 percent feeding. Just a FYI. Hope this helps someone.

Comments and Suggestions: I have 10 of these KCI .40 mags, for anyone having problems with there mags take the bottom plate off look inside mag halfway up you will see some plastic that needs to be removed take a sharp knife and scrape excess plastic till inside of mag is smooth... I have 10 of these mags and they perform flawlessly after step above is completed. Also load mags 15 rounds over night.. then next day load to full capacity, and blast away... Hope this helps someone.
