No--I haven't used Wolff springs in my mags. Only Glock replacement springs. Personally, I don't think an extra power spring is going to help your issues. I would imagine the 10% extra power would either be made up of a larger diameter wire, a redesigned wire, or a different annealing or heat treating processes above and beyond normal manufacturing--just a guess. I use grip sleeves on my G23 magazines that I use specifically in my G27 since I don't own a G23 and they work flawlessly-loaded to the max and down to the last round. I'm still thinking your problem lies with the alignment of the longer mags in the short well. Realize that a full or mostly full mag would probably align itself pretty well, but as the mag empties and gets closer to the last round, becomes sort of sloppy. I haven't tried my G22 mags in my G27, but if I did, I'd bet I would have the same problem s as you are having. Even an empty G22 mag weighs more than an empty G27 mag. It only takes a hair for the follower not to push up on the slide stop, it only takes a hair for the slide not to strip a round off the top of a mag. Anytime one knowingly uses non-specified parts in anything, they can expect to roll the dice. I know you'll be getting some of the Wolff springs, and I truly hope that helps. I'd be interested to see the results.Has anyone put Wolf springs in their Glock mags? Any problems loading rounds or loading the mag into the gun? Feeding issues? Is a Wolf spring longer or is it just more stiff? Any feedback that someone might have would be appreciated.
