My 938 came with the extra bulbous, rubber grip and the pinky extension magazine.
I liked it the first time I tried it.
The main thing when practicing with it is concentrating on how much finger to use.
I have never pre-maturely ejected my magazine. Probably a grip location/ergonomics thing.
Downside, the guide rod is a threaded two-piece deal. With time it might come apart and fly out the end of the gun. If it does, Sig will send you another guide rod and recoil spring. I always check to make certain mine is tight when I clean it.
