Para P14 mags in a P10?

[MT60]

Anyone have any experience with using Para P14 mags in a P10? I have the P10 and, at the urging (some time ago) of the dealer I bought the P10 from (new), finally bought a new P14 mag from Para for the added capacity. It fits the mag well, of course, and engages all the catches as one would expect. It does not, however feed reliably. A little online research indicates the most likely cause is the spring in the P14 mag won't feed quickly (or perhaps better stated 'forcefully') enough to work with the increased slide speed of the P10 and its 3" barrel. There were a couple of posts (not here) that indicated a nice heavy duty Wolff mag spring fixes that right up. It's seems reasonable, and its not a huge investment, but it would sure be nice to hear from someone who's been there and done that before I put any energy into it.
