Works great, exactly as aa states - Advantage Arms Glock 26/27 .22 LR Conversion Kit w/10-Round Magazine and Range Bag

Installed on .22LR Conversion kit on stock/base Glock G26 Gen 4. The side of the slide of the conversion kit I received has "26/27 LE" stamped on it. The slide looks very much like the OEM, which is what I was going for. It is great that the conversion is simply just removing the OEM slide with spring and installing a complete slide with spring, and then just using different magazines. Started with the ammo that Advantage Arms (AA) recommended, and the kit functioned very well and reliably. I did not perform any accuracy test, as this was not a purpose for this acquisition. I then progressed to some very old (like 20+ years old) that was gifted to me that was not recommended by AA. Most did cycle, while many did not fire. (This was bad ammo that I was just trying to go thru, and figured why not try it in this kit.) In addition to the barrel, assembled upper slide with spring, and a 10-rnd magazine, it came in a very nice softly inside lined case/bag with handles. There was plenty of room with pockets for additional magazines and ammo in the bag, as well as very explicit instructions on recommended ammo, generally acceptable ammo (and the issues one may experience with such ammo), and list of not recommended ammo.
Overall, since it was well communicated the kit was ammunition particular by AA I understood what I was purchasing, and am quite pleased with the kit. It is a great training kit that saves on the cost of ammunition with training. I used it to allow my young nephew to try something that is easy to handle with very little recoil (relatively speaking), so that he could learn proper firearm handling and usage and not potentially develop a shy-ness to handguns. Also, since the kit allows for a much smaller caliber, this allows targets to last a bit longer compared to using OEM caliber. I do recommend this conversion kit for the Glock G26 Gen 4.
