If you have some of the smaller baseplates that don't protect the mag from being overly inserted bending your ejector, buy these base plates. These base plates will protect your $2,500 investment. These problematic bases are older mags with short base plates that show steal when inserted. I bought a couple but not enough, my gun will head back to Stacatto and their great customer service for repair. I expect.

Excellent base pad for the Staccato 20 round magazine.

The 10-8 140mm magazine base pads fit and function just as advertised. No worries about over insertion or bending of the ejector. Highly recommend these base pads.great job on all your products Hilton....5 stars.

It's a base pad. Has dimples for marking which is fine. The best part is that it holds the spring and follower in the gun. A+

I've had every generation of Staccato base pad, including the latest Dawson Precision pads, and these are definitely my favorite. The large divots on the sides give a good purchase when running the gun and the aggressive serrations on the front of the mag give tremendous grip so you can easily rip out a mag to clear a malfunction. These basepads have way more traction than all the other basepads I tried and I carry these for CCW, gaming, and on my warbelt for when I want to larp around in multicam. I only wish there was the option to buy mags with these already installed. Regarding fitting, the size and profile of the base pad works with the Dawson Precision Tactical Advantage magwells, so they are an easy swap. You can use them with the STI slim tactical magwell, but you'll need to take a a half-round file to the magwell first to open up the magwell in the front corners and then slightly widen the magwell opening down the sides. The process isn't that hard and you'll have a magwell that will work with any basepad when you are done. I haven't tried these basepads with the TTI magwells yet, but I assume that would be just as easy to fit. The star button Staccato/DP retaining plate is a little hard to fully seat and I found it easiest to just fully load the mag and give it a hard tap to fully seat the rounds and the base plate. It is good to go after that. The round button retaining plates on the TriArc mags fit and lock in perfectly and I personally wish Hilton offered those retaining plates for sale here as I can't find them for sale by themselves anywhere. I think the star on the Staccato retaining plates have the potential to get crud stuck in them and even though they look cool, function and performance comes first.

Outstanding product, flawless machining and finish. Really like the deep thumb divots on the side but especially the front serrations that definitely add to functional grip if you need it. Size is perfect for 20 rnd mag to seat flush with grip on full size 2011. More importantly, you will not find a more professional and passionate craftsman than Hilton. The kind of people you want to do business with and recommend highly.

I have not gotten them yet. Usps sucks, I understand it is not 10-8 fault. I have other 10-8 base pads and I love them, I'm sure I will like these as well.

This is the second order of these. Easy install and great product.

Great product, easy install. I will be buying more. Great Tactical look as well

These basepads are substantially better than the plastic basepads that come on 2011 mags, and a very reasonable price point. I didn't read the note about them only fitting the new magwell geometry, but with pretty minimal hand filing of my magwell (on a DVC Omni) they now fit and function flawlessly.
