Just picked up a used G27, it came with 2 standard size mags. I picked up a .40 caliber high capacity mag at the gun show yesterday. I bought the mag to use as a back up since it sticks out beyond the frame. At the range the last round from the high capacity mag FTF, it only exits about 1/4" from the mag. I suspect the mag spring is weak since it doesn't take as much force to compress the follower as it takes to compress the smaller mag. I noticed that the shape of the followers is different between the hi capacity mag and the standard capacity mags? The follower on the high capacity mag has a "5" engraved on the top, the standard capacity follower has an "8" engraved on the top. I'll attach a photo. Do I need to change the follower too?
