The R9 Recoil Spring
Assembly
|
I am adding
this page for two reasons primarily. One is
to ensure that people are aware of the components
and the correction orientation of the main
spring.
Secondly, it is worthwhile to be able to see
if the inner guide rod should ever become
loose from its threaded attachment to the
mainspring retaining collar/disk. This is
normally secured and should not loosen but
if it does, then effectively the critical
guide rod length increases - which is prejudicial
both to function and pistol structure.
Most recent thinking on spring replacement
is every 100 rounds, to absolutely ensure
the gun does not get beaten up, tho I certainly
doubt running on beyond that somewhat is seriously
prejudicial. It should be remembered this
is not a recreational gun per se - it is for
carry primarily. |
Here is a picture
of the disassembled components - it has had to be
further reduced to fit this page so apolagies for
the text being a little less than sharp.
Note - this picture shows an abnormal appearance
to the retaining disk - it was at the time of photographing
a half turn loosened, although it was reluctant to
unscrew any further. Even this half turn represents
a significant increase in length of the total inner
guide rod assembly.
When cleaning the gun after takedown, inspect this
carefully, to establish all is well. The end of the
inner guide rod threaded portion should be effectively
flush with the rear surface of the disk. Here it appears
inset, that is the half turn - enough to notice. Furthermore,
inspection of the inner guide rod about a quarter
inch away from the disk will show a gap if loosening
has occurred - normal fit will only show a barely
perceptible join line.
If loosening has occurred this should be regarded
as reason to return the guide rod assembly to the
factory .. it requires I believe a strong thread locker
to secure - probably after full disassembly and thorough
degreasing. If in any doubt, contact the factory.
