Recoil springs. Conventional vs. Variable?
#1
Posted 11 September 2009 - 07:17 PM
I just got my new open gun running. It has a standard length slide. 38 Super running 115gr MG JHP's at around 1470 fps. It has a 9lb conventional spring in it right now. I was told to try a lighter spring in order to allow the comp to work better. My question is should I stay with a conventional or should I use the variable recoil spring. I know that the FAQ on Wolff's web site states that variables are good for compensated pistols. I know that everyone has their own opinions and that it is just a personal preference. I am just wondering what everyone is using here?

Thanks for the response. I am just wanting personal experience and opinion. I had thought about making it a poll, but there seems to be some hostility towards polls here for some reason.

I use straight rate springs (made by Sprinco) in my Open guns when I run normal springs... Currently playing around with a Recoil Master.
Note, I have no affiliation with Sprinco - not that it would do me much good. I've never worn one of their recoil springs out, so a sponsorship would be worth about $8 to me...
(yes, they're that darn good!)

I use a straight 9lb ISMI in both of my Open guns using a load similar to yours (slightly hotter, but not much). I don't believe the idea of a spring making any difference in how the comp works. Slow motion video of guns shooting shows plenty of gas exiting ahead of the bullet and the slide and barrel are still locked up.
Assuming the gun is running properly, if the dot is tracking well for you and isn't totally leaving the glass I wouldn't worry about it.
Hmmm...I haven't seen a hostility towards polls. I've started a number that had plenty of mods replying to.

When I shot open I shot a similar load and I liked an 8lb variable spring. Heavier than that and the dot started to dip. I liked variable because I could run a heavier spring without the dot dipping, they seem to be let the slide close up a little softer.

I'm curious to know how long or how many rounds does everyone shoot until you replace the recoil spring in either Open or Limited?
Personally, I replace my conventional recoil springs after about 1,000 rounds.

I'm shooting a 9lb ISMI in my current set up. I feel (note this is subjective) the ISMI springs last a bit longer before taking a set. I've used both variable, and straight, in both my limited and open guns, and don't see a big difference. Plus one to what Gman said about the spring effecting the comp.
I shoot the piss out of my guns, I'll change springs a week or two before a big match, and I'll probably shoot one to two thousand rounds a week before nationals.
