Lower # Recoil spring on a P-09
« on: November 14, 2017, 09:10:29 PM »
Looking to the experts to educate me.
What are the advantages to a lower weight recoil spring in a P-09 ??
Have you done this and what are the results compared to factory?
I am also putting a Vortex Viper on the slide.
My pistol is for  self defense, I don't do any competition but may in the future.
I generally shoot for Target ,Factory loads 124 gr.
I carry Federal 147 HST.

My P-09 functions great with the factory spring.  It would cycle weaker Perfecta ammo when my P-07 wouldn't. 
Others more knowledgeable than I should chime in soon but for my use, the stock spring has been fine for thousands of rounds.

My question wasn't whether the factory spring was any good , I just wondered if anybody went to a lighter spring and why.

I have not.

I don't shoot any "target" ammo in mine so I'm afraid of damage, over time, to the slide/frame if I ran a reduced power recoil spring.

Lots of people do run reduced power recoil spring for target/completion shooting.
Better to have it and not need it, than to need it and not have it.  So, if you see me walking the dogs with my SIG 556R, its okay.

As I understand it...if your second shot hits consistently lower than your first shot (with relatively low split times .20-.25 aka actually aiming) then you could try a lighter recoil spring.  Heavier spring will sling-shot the slide forward harder which causes the second shot to dip lower than needed. 

A lot of it depends on your grip and your load.  124gr target loads vs 147 HST defense loads would, I assume, recoil differently.  I went with the Cajun recoil rod and 15# recoil spring for my 132-135PF loads and it is perfectly reliable.  Cajun also has an 18# spring for that setup which I would guess goes better with the defense-type loads.

I'm not concerned with minor PF loads beating up the frame on a P-09.

15# spring: https://cajungunworks.com/product/15rs-recoil-spring-for-p-0709/   ($6)

18# spring: https://cajungunworks.com/product/18rs-recoil-spring-for-p-0709/  ($6)

"TECH TIP:  There are 2 methods for selecting the correct recoil spring.  The most common method is based on the ejection distance of a fired case.  Ideally, the case should land 6-8 feet from you stance.  This  method allows your CZ to achieve the correct slide velocity that is critical for extraction, ejection, feeding, and slide lock.  The other method, for competition shooters, is how fast your sights re-align with the target."

mine easily eject 6 to 8 ft.
 so what I'm understanding is, special guide rods and lighter springs are mainly for competition shooting. But can be used in a self defense firearm. Thanks for the info guys.
