So you have polished as describbed in the pics, and if I understand correctly, you have removed the small pig tail spring, but have left both the inner and outer coil springs as they were?
Now this is where I get a little lost. This spring you describe as being similar to that of a ball pen type, does it replace the pig tail spring?
No Rocketman....the little pig tail is removed...."some" say it is a direct
result of the S&W Glock settlement (from S&W obviously copying so
much of a Glock, and that it wasnt there on very first Sigmas and only showed up till after legal issues...? ) others say its there to help ensure
sear resets after each shot...?
No, the "similar" to a pen spring mentioned, when you look, is actually
a LARGER spring that totally rides over, a smaller diameter INNER spring,
with much more tension, and actually does the work..the outer spring seems really there to keep this inner spring in check and installed..etc..
When I obtained the mod(s) originally and pics from S&W forum...the
mod actually shows taking inner smaller spring and using a dremel wheel
disc, shortening it by "almost" 1/8 inch, and also same to outer spring...in
order to reduce some pull....
I do not endorse changing the INNER spring at all, for possibility of indeed
affecting sear/trigger reset, but I do or did change the outer...most indeed
just got a ball point pen soft spring to replace with...however, I searched and found a "grab bag" of industrial compression and expansion springs
and found one same length. but half the tension...etc...but..a ball pen
spring would have probably done the same. I placed "original" outer spring in
little bag with factory proof case should I ever transfer weapon, however
if any have read My Sigma post...is obvious I will not get rid of this
Please contact me with any further questions or comments...thanks..
note per pics I added....
- I annotated about cutting outer spring as he explained...but...I didnt
and actually got a different and SHORTER (less tension) spring...and did
nothing to INNER spring. This way, "some" trigger/hammer pull was reduced yet important INNER spring still held in place....
And the grind wheel was to flatten any cut so a spring if shortened would STILL have a good area or foot to catch the little cam that holds it in
place in "hammer" assembly .....?
