    Anyone know the # of the M-9 recoil spring?

    no idea. but if you could cook up a way to make it stiffer, i'd be all over it.

    my buddy uses a glock 19 spring in his, but has issues going into battery sometimes. that spring is a higher rate, but with less preload.

    i thought about cutting a few coils off and putting a spacer in there, but you're doing the same thing, increasing rate and decreasing preload. plus, i think they used a flat spring because there isn't very much room to start stacking something during recoil. ie, if you stick a spacer on there, the gun might not cycle fully to the rear.

    are you cooking up something?

    BigT, you know me, I'm always up to something. Last night, I started to mess around witht he M9 and I ended up Duracoated the slide black, looks much better than the parked finish. Not the best job, still learning Duracoat...

    Then I got my #2 swiss pillar and fitted a new Beavertail onto my Kimber, I have the new BT for a while but just stalling and didn't want to mess with my Kimber. The stock one is just abit lacking in a asthetic, this CMC ones rides higher and looks much better. I need some final polishing and contouring and gonna Duracoat it Combat Grey or what's that in vogue color...Earth Brown.

    Then I had an Einstein moment, I read on Don's guiderod forum (Don built guild rod for XDs) that a too heavy a recoil spring is indicative of shell in the face syndrome, exactly what I have. I just want to see what would happen if I mess what the recoil spring weight.

    i never knew that the recoil spring could cause that.

    most of the people that post about that seem to report that brass-in-your-face-ness goes away after a good extractor cleaning and @500 rounds.

    i want a stiffer recoil spring to ensure battery (not that i'm having trouble mind you) but mostly to make the gun shoot even flatter.

    i don't know jack about 1911s. never really my thing. i should really squeeze off a few with somebody's race gun at the next ipsc shoot. i think it's cool just watching the smokestack coming out of the compensators.

    i mean, i got beavertails, but don't talk recoil spring rates for .38 super vs. 9mm.

    but it's kinda like crack. i never tried it cause i knew i'd like it and get hooked.

    one of these days, right after i build the 1st 100 projects on my list, i'll do a race gun. til then, production will have to do.

    BigT, Thats just what I heard about the stiff spring cause that...who knows.

    It kinda make sense if most people report that after 500rds or so the ejection correct itself=recoil spring loosen a bit not as heavy...maybe it just a # or so difference!

    I have 500rds in it but it still throws them all over the place.Sometimes to the left of me!?!? I don't know, I'm just tired of eating shells. Them shells put a couple of scratches on my brand spanking new Oakley. I'm PISSED.

    I put a heavier spring on my Para Ord P13 and started catching brass in the face. I went back to the stock spring and it stopped. I think there is truth to what you heard.

    I'm tempted to get guiderod and stick an extra SIG 226 spring I have laying around and see what happened.

    Has anyone tried a Glock 17 Spring?

    Someone has got to have access to one... I do, but I don't have my Steyr yet :D

    As soon as I can get a JackAsh rod I am going to be doing much experimenting.

    It'd be nice if WOLFF could cook something up. Anyone ask them?
    If not I could fire an email off their way... on second thought I will do that right now :)

    glock 19 spring will work if you get a guide rod.

    but... the relationship of spring weight vs. preload is not ideal for the steyr. i'm not sure what the numbers on either spring are (i really should find out, huh) but, the g19 spring doesn't give a good solid lock into battery.

    forced into it i'm saying the g19 spring has a higher rate but that in the steyr it has insufficient preload. the gun definitely shoots flatter, less muzzle flip, but he gets light primer hits from firing out of battery too regularly.

    maybe you could design more preload into the guide rod. just have to watch that the spring can compress enough to cycle the slide.

    pittwm, this may be way out there, but when I fixed my fte problem by stiffening the extractor spring, my "brass all over the place" problem went away, too.

    Now it lays the brass into a 4 ft circle at my 3 oclock.

    Sure is nice not to fish brass out of my shirt pocket!! 8)
