I have a Springfield PX9503L - commander length slide 4”, officers size grip and alloy frame - I love this pistol!
This pistol has a 2 spring recoil system. A small spring rides on the guide rod and is captured and covered by a sleeve. The second longer spring slides over the sleeve that the small spring is inside of and is captured by the plug in the slide. The 2 springs can never touch each other. This system is just like my Kahr PM9.
I have @ 1,500 rnds of mostly 200gr swc that are lighter charge than say 230gr Federal HS.
Lately I have had a few failure to battery with the 200gr swc - which do not chamber as smoothly as round nose or hollow points bullets. Its also not ejecting the cases the same place it used to do. Up until now I have never had any problems of any kind no matter what ammo I fed the pistol.
I think my recoil spring is tired/weak and would like to replace it.
I have noticed that the small recoil spring on the guide rod is no longer long enough to keep the sleeve against the guide rod stop. I now have @ ½” of slop - it used to all be under tension even at full extension.
All replacements I have seen, except for Springfield factory assembly, are all 2 piece guide rods with 1 spring.
Is the one spring setup better than the two or just a marketing thing?
I was looking at Wilson combat guide rod-plug-spring kit #25SC or considering just getting another duel spring setup from Springfield.
What scares me is that the Wilson site says springs should be replaced every 300 rounds with compact .45‘s. Also the Wilson kit says it comes with 24lb spring but all single replacement springs they sell for this application are 20lb or 22lb - not 24lb. Springfield spec says 22lb.
What life should I expect for factory duel or aftermarket single spring?
What does experience/history say is better duel or single spring?
Thanks
