(7 customer reviews)

SKU: N/A Category: Tags: ,


Only Fits:

  • Sig Sauer P365 / 9mm
  • 10 Round magazine ONLY


  • Every Day Carry


  • Extends .7″ below bottom of grip
  • Tolerant of repeated dropping
  • Added weight aids in magazine release
  • Made from 6061 Aluminum
  • Hard coat anodized

An improvement over the polymer OEM base pad, our P365 Pinky Extension is machined out of 6061 aluminum. They are much more tolerant of being dropped on rocky or cement surfaces for heavy tactical or training use. The added weight of these base pads also aids the magazine in dropping free from the magazine tunnel for rapid and consistent reloads. The extended magazine gives the shooter a more robust grip. Great for big hands or those shooters wanting a fuller grip for their Sig Sauer P365.

    You have nailed the 10 round extension to a T!!! I ordered 2 to try and they are perfect. I’ve tried others and there is no comparison. Just ordered 2 more. If they were a little more economical I would outfit all my 10 rounders all at once. No matter. Just take a little more time for all 8. I’m willing to pay for a quality product and this one is it. Great job guys!!!

    I don’t think $29 is a realistic price because the material is the same and the p230 ones cost only $12! I would buy two if this item had a fair price!

      Yes the material is the same as our other base pads however the construction of them is not at all the same. There is a lot more work that goes in to building a base pad that will attach to a P365 magazine. We charge the lowest price we can base on manufacturing cost.

    Really nice addition to the P365 I chose to swap the stock pinky extension for this Obsidian Arms one and am super happy with it. Adds a bit of weight for quicker mag extraction, really nice at the range and also adds a nice touch. I ordered mine from Lakeside Gripworks and had it cerakoted in OD Green. Came out awesome!

    The P365 Pinky Extension does not add additional capacity.

    Really nice fit on the 365!! Great quality as well!!
    I see a few comments on price…its 35 bucks people…that’s dirt cheap for a great quality product. If you want cheap go on EBAY and order something made from China. These guys sell great product for a very reasonable price.

    Perfect fit for the 365. It feels that I now have a solid grip on the handle. Simple installation looks great on the on the P365. I have a big hand it makes the compact carry feel a lot bigger than it is, but it does not increase the size.

    Very well made product. Looks and feels great. I have a lot of people ask me what extension it is and I always recommend it. You guys nailed it. Will be ordering more of these very soon!!!
