I recently bought a Glock 19 and 26 to compliment my 17. My Glock 17 has been 100% reliable with all ammo and mags. So were my 21 and 30.
I noticed that both the Glock 19 and 26 will fail to feed from the 33 round Glock 18 mags I have. Both mags have this problem, about one failure every 3 shots. This is with Fiocchi 115gr FMJ ammo. The 33 rd mags are flawless with WWB and Remington UMC. They have been 100% with all ammo, including the Fiocchi, in my 17.
When shooting, the slide will close on a new cartridge and dent it about 2mm from the rim, with the bullet pointing upward. It seems like either the slide does not move back far enough, or the mag spring doesn't move the next round up in time to be chambered. Or both?
Anyone noticed a similar problem?
Also, I noticed the 33rd mags are difficult to insert in the Glock 19, because of two small rails molded into the magwell. The 17 and 26 do not have these. Glock 17 and 19 normal capacity mags have a groove near the rear of the mag to clear these rails. Any inside info on the purpose of this?
Thanks!
