    A great product worth waiting for

    I finally got these to use in my Magwell equipped X-ten when I got the long backordered couple extra Factory magazines. They are nice and stout and have some weight , just right for positive mag drop and help with recoil and won’t break when dropped on concrete . These work without the Gray Guns magwell , but of course are designed to work with it . Hint: if ever mag capacity laws are upheld , I learned in California a pop rivet of appropriate size can be put in the mag at appropriate depth to limit capacity . Since this requires a grinding tool to be removed it is considered in every case so far to be a permanent feature and comply . The attachment of this extension is beefy and easy to install .

Many parts sold by Grayguns - including but not limited to triggers, trigger kits, internal components and spring kits - are intended for installation by a qualified armorer or gunsmith who is familiar with the firearm.

Although kits fit with no issues in a great majority of pistols, Grayguns cannot guarantee perfect functionality in every instance.

Due to varying tolerances present in all mass-produced firearms, professional fitting by a qualified armorer who is familiar with the pistol's action may be required.

Grayguns offers installation services for all parts kits we offer. If you have any issues or questions about the installation process, STOP IMMEDIATELY and contact the Grayguns Customer Service Team.
