Does it match the slide and frame by proper fit and/or serial number?
Recoil Spring and Guide
Inspect the spring for straightness, continuity of the wire wraps, equal separation of
the individual coils and proper fit on the recoil spring guide.
Inspect the spring guide for smoothness, straightness and flange integrity.
INSPECTION continued
Frame/Slide
Inspect the frame and slide for the appropriate serial numbers.
Check the sights for visible damage and proper fit in the dovetails of the slide.
Verify that there are no abnormally protruding pins from the slide or frame.
Visually check for cracks, excessive wear or stress marks.
Verify that all screws are in place and tight.
Check the grips for proper fit and damage.
FUNCTION INSPECTION
Safety is the first order of priority when performing a function check.
A function check is used to verify the proper working order of all mechanical features of
an unloaded firearm. This may be accomplished by proper weapon handling and the
removal of all ammunition from the work area. Check the firearms and the work area a
second time before proceeding.
The magazine, frame and slide will be checked simultaneously.
The magazine should be inspected as previously described for serviceability. The first
step in the function inspection is to insert the magazine into the pistol, ensuring interlock
with the magazine catch. The automatic lock back of the slide is verified by pulling the
slide completely to the rear to verify proper engagement of the magazine follower and
slide catch lever.
The magazine should fall free from the pistol of its own weight when the magazine catch
is depressed. This verifies the correct relationship of the magazine, magazine catch and
frame of the pistol.
The slide should spring forward without hesitation as the slide catch lever is depressed.
This verifies correct engagement and release of the slide catch lever in the arresting
notch of the slide. Additionally, it checks that the slide moves freely on the frame and that
the recoil spring has the strength to close the action.
Moderate thumb or finger pressure should be exerted on the spur of the hammer while in
a cocked state in an attempt to push it forward. The hammer should remain cocked.
This shows that correct hammer/sear engagement is being maintained.
