That would be a Glock 43 that takes Glock 26, 19, and 17 magazines. I have heard you can use a heatgun to fix the Glock Pig-nose. So why not replace the narrow 43 magazine lock/release with a wider 26. Then heat the frame until it will stretch and take on a new form. Shove in a lubed up, cold 26 magazine until it locks in place. Let the gun cool and POW! A Glock 69! Hey. You only need about a 1/4'' more width? Edit: 43+26=69 There is nothing sexual meant by this model number. You sick little monkeys! Of course I would first like to try this with your Glock 43.
