Ergonomic and sturdy, this high quality pinky extension looks great and is sturdy.  Printed on Mark Forged 3D printers for the best possible strength and appearance.

Get the same grip size and support as using the 13 round magazine with your 10 round magazine for capacity limited states.

Its snug fit into the frame eliminates the potential for pinching in our testing.

Pistol and magazine shown for illustration only.  Only the plastic pinky extension is included.

    Full length hellcat 10 round magazine extention

    Posted by Nathaniel Greene on 15th Feb 2024

    I have larger than normal hands and the pinky extension was doable but I have been looking for a little more surface area to side in my grip. This product does just that, same length as the pinky extension but more of an entire gripping area. A little tricky to install but it can be done with a small screw driver (also a video on YouTube which will help). I fired it today and these extensions did not affect the overall performance of the weapon. Mag does seat better with the chamber open, but it can be seated with a little extra force when the chamber is closed.

    No pinch full length extension 10rd Springfield hellcat

    Absolutely perfect. The fit is amazing. No pinch and no rattle. Fits better then the original finger extension. Highly recommended and will be buying more.

    Nice grip for the 10 rd mag

    Posted by Vinny on 3rd Jun 2023

    Makes the 10 round mag have the length of the 13 round mag. Nice for states with capacity limits. Just need one a little longer now to emulate the 15 round mag.

    13 round pinky extension

    Fits perfect. I hope in the near future you can make one the size of the 15 round pinky extension to fit the 10 round mag.

    Perfect Fit

    Posted by George on 7th Mar 2023

    This extension is exactly what I was looking for. Fit on easily and gives you enough room to get a full grip on it. Texturing is really nice too. It is a bit pricey since you have to pay for shipping and a brand new pinky extension magazine is $34. Still recommend it if you want to update one of the flat baseplate mags.

    A must have if you have big hands.

    Posted by Danny on 9th Feb 2023

    I live in a 10rd capacity state, when I purchased my Hellcat it came w/a pinned 13rd mag & one 10rd mag w/pinky extension that is okay but not enough for a solid grip. These extensions were a lot easier to install than I thought. Literally snapped them on in about 15-30 seconds each. They make gripping & drawing out of the holster a lot smoother. From time of this review, I ran about 600+ rds with them. No feeding or ejecting faults. A must have if you have big hands.

    Like factory

    Posted by Bill on 16th Dec 2022

    If there is one thing I love, it something that feels like it belongs on a firearm. I was skeptical at first that these would feel like the grip on the firearm and I commend them for this. Feels just like the factory (or pretty damn close) texture as you would get on a Springfield pinky grip. The added length without adding rounds to a 10rd mag is great!

    10 Round extension

    Posted by David Kenyon on 18th Nov 2022

    Fits nicely, gives a better feel for hand hold. Defiantly recommended addition if gun feels a little to small for hand. I found I needed to hold spring down while installing.
