My challenge and concern with this is that the JRC is obviously marketed to the law enforcement community and some agencies will undoubtedly purchase it for issue as a “patrol rifle.” (For the sake of understanding, if the long gun is chambered for a handgun caliber, I don’t consider it a rifle. The published information from JRC indicates that you should push the magazine in until it clicks in place and then pull on it to insure that it’s positioned properly. Apparently, if you slap the Glock magazine into the JRC long gun, it’s possible to seat the magazine too far in and thereby create potential feeding malfunctions. The one that most caught my eye was apparently caused by seating the magazine into the JRC too far. On the Just Right Carbine webpage you can find some informational PDFs that discuss potential malfunctions and their causes.

Prior to any cross-magazine testing I did some research. While I’m not a fan of using 30+ round magazines in my handgun, having them available for my long gun would be preferred and being able to use them in either is a desirable versatility (in my opinion).įor my testing purposes I had on hand a fourth generation Glock Model 17, a Just Right Carbine (JRC) designed to use the magazines of the Glock 17, and eight magazines for said Glock 17. Yes, you can buy factory and after-market magazines for the Glock 17 that hold as many as 30 or 33 rounds. Yes, you can get +2 floor plates for the magazines giving them an increased capacity of 19 rounds. Standard Glock 17 magazines hold 17 rounds of 9mm ammo. In this case we’re talking about the Just Right Carbine in 9mm that uses magazines for the Glock Model 17.

The benefit to this strategy is that you can have an effective handgun and a (relatively) effective long gun and if you have spare magazines for either you have spare magazines for both. The down side of this is that you are restricting your long gun to a handgun caliber (the one arguable exception being the 5.7mm pairing). The most often cited reason I come across is compatibility of magazines the ability to use the same magazines to feed the handgun and the long gun. There are several reasons why someone might want a long gun and a handgun in the same caliber.
