Polymer Posted August 15, 2016 Share Posted August 15, 2016 What is consensus on stock 2 recoil spring weight with 147 gr at around 130-135 power factor? I just purchased a stock 2 and have found there are quite a bit of choices/opinions. Link to comment Share on other sites More sharing options...

You're by far the lightest of anyone. Have you tried multiple weights and that's your preference? Link to comment Share on other sites More sharing options...
johnbu Posted August 16, 2016 Share Posted August 16, 2016 I have an 8 in each s2, but I cut coils to my own unique tastes. Link to comment Share on other sites More sharing options...
johnbu Posted August 16, 2016 Share Posted August 16, 2016 Yeah. ejection is a good indication of springs. But... a person i look to indicated that many people overspring and wind up with muzzle dip from foreward slide slam. Imho, ejection of brass only tells part of the story (a big part!, but only part) Really good thing is to film a bill drill of the gun, with a horizontal marker to watch muzzle rise and fall. that will show how much flip n dip the gun has with various springs vs loads. An OCD person could go nuts with different springs for 130PF using 124, 135 and 147 gr projectiles. Ahem...not that I'm OCD...! Much. Link to comment Share on other sites More sharing options...

Ben Stoeger told us in May that he ran a 6 pound spring in his S2's while he was here for a training class. Link to comment Share on other sites More sharing options...
cjdaniel78 Posted August 16, 2016 Share Posted August 16, 2016 In May 2015 he told us he used a 10lbs. I suspect he runs a 10 in his training guns but a 6 in his match guns. I know he runs a heavier trigger in his training gun. Link to comment Share on other sites More sharing options...
johnbu Posted August 16, 2016 Share Posted August 16, 2016 Actually, I thought he runs pretty uniform trggers across his guns. was in his class a couple weeks ago. The guns of his that I fondled were pretty vanilla. Probably 6 - 6 1/2# da and 2 - 2 1/2# sa. Didn't ask, just what it felt like. The slide was very smooth, I thought it was about an 8#...but didn't ask Link to comment Share on other sites More sharing options...
bigbob21 Posted August 17, 2016 Share Posted August 17, 2016 Either pro's run 8s or less or I have weak grip strength... I dunno how you guys do those "show me clear" motions with just your thumb and webbing over the slide... I run a 9lb and it's doable but I just use the rear serrations... also... Ben shoots 124s not 147s, so that might affect it a bit... Link to comment Share on other sites More sharing options...

Robmorfrau Posted August 17, 2016 Share Posted August 17, 2016 I use the #9 with my S2, I run RMR 147g 130-133PF. Gun Feels a little sluggish with the softer springs. Link to comment Share on other sites More sharing options...

If more, wouldn't there be more recoil defeating the purpose of making our own loads? And with less power factor aren't you at risk of failing chrono? Or are we just unlucky and everyone shoots 130pf Link to comment Share on other sites More sharing options...

I tested the 8# and the gun felt sluggish.... my opinion is that the 9# is soft enough to avoid dipping / unloaded starts etc Sent from my SAMSUNG-SM-G900A using Tapatalk Link to comment Share on other sites More sharing options...

I rack everything that way (the web between thumb and index finger over the slide) which includes Glocks with factory springs and my M&P USPSA gun at the moment, with a 13 pounder. (Yeah, I know those external-slide models are generally easier to hold onto than slide-in-frame CZs and Tanfos, but I've always racked them just fine this way too) I don't think I have exceptionally strong hands, but then, I do work on heavy equipment for a living.

johnbu Posted August 18, 2016 Share Posted August 18, 2016 That's exactly true! It's as much about feel as anything. I do mine to get them to FEEL right to me. everyone should do the same! my perfect feel won't be acceptable to everyone. that's what makes tuning fun (my opinion) 10 hours ago, emjei said: I have to agree here....

eboadway Posted August 18, 2016 Share Posted August 18, 2016 Bullet profiles vary widely. I can load Xtreme's to 1.15, but Blue Bullets max out at 1.11. p.s. thanks for the Bolo's, working great! Link to comment Share on other sites More sharing options...
Dr Mitch Posted August 19, 2016 Share Posted August 19, 2016 It probably depends on the shooter. I was using an 8lbs spring, but ended up with more consistent returns to the same sight picture with a 10lbs spring. Link to comment Share on other sites More sharing options...
bigbob21 Posted August 21, 2016 Share Posted August 21, 2016 I recently tried an 8lb vs 9lb and they both feel the same to me...(recoil/sights returning, etc...) Ran a 100 rounds through a 6lb (after hearing Eric uses one) and it feels weird... Maybe I can describe it as some have said they're guns feel slugish? I'm not the fastest shooter around here, but I don't see a problem with split times and the "slower" spring return... The sights return just fine? The recoil impulse just feels weird... Was going to try and run it in a small match today but got rained out... Link to comment Share on other sites More sharing options...
emjei Posted August 21, 2016 Share Posted August 21, 2016 Correct me if Im wrong. ...... Does Hammer Spring Weight influence Recoil too ??? Even the Magazine Spring play a role tooSent from my SAMSUNG-SM-G900A using Tapatalk Link to comment Share on other sites More sharing options...
EngineerEli Posted August 22, 2016 Share Posted August 22, 2016 I suppose the mag springs effect how much pressure the top round in the mag exerts on the underside of the slide rib, effecting friction and slide velocity... Hammer spring weight certainly effects the feel of recoil as does the curvature of the firing pin stop. Stronger spring or more squared off firing pin stop, will give slightly more initial muzzel flip, but will keep the slide velocity lower meaning less flip when the slide bottoms out on the frame. This is generally more desirable for major PF though. Minor tends to run smoother with more rounded firing pin stops and relatively lighter hammer springs. The concept still applies though. It is possible some people using 6 or 8 lb recoil springs are in fact using heavier hammer springs to balance things out... Link to comment Share on other sites More sharing options...
bigbob21 Posted August 22, 2016 Share Posted August 22, 2016 hmmm so light recoil spring and light hammer spring = not the most benefit? finally got that 10lb PD hammer spring in and a bunch of federal primers Link to comment Share on other sites More sharing options...
