To
determine if your NEOS requires service, you can inspect
the firing pin currently installed in
your U22 NEOS.
Please
refer
to
the
materials
below. Note that the firing pin is indicative that your U22
NEOS requires service and is not the only component replaced
as part of the servicing process.
Visual
Characteristics of the U22 Neos Firing Pins. There are two means to check your firing pin - in the
firearm or by disassembly.
In
the Firearm Method: Observe the back of your firearm
and compare the firing pin to the images and descriptions below:

you owners
manual (pdf) and and then follow the additional steps
shown to the right to gain access to your firing pin. Once
you have removed your firing pin, compare it to the images

pin.
Disassemble your NEOS per your owners manual.
Support the front end of the firing pin and release the trigger.
Remove the firing pin and spring.

As depicted

sharper cut in the shoulder in the front area of the firing
pin. If

contains this type of firing pin, you do not need to send it
in for service
The
video on the right explains the differences between the firing
pins and how to inspect your U22 NEOS with the firing pin installed
inside your firearm.
