Duane Thomas Posted August 6, 2004 Share Posted August 6, 2004 I don't run a shok buff, because if you have ever had one come apart, your stage is over. " if it can break it will" Truer words were never spoken. Link to comment Share on other sites More sharing options...
davidwiz Posted August 6, 2004 Share Posted August 6, 2004 Since everyone is chiming in - in my .40 I'm running a 14# recoil spring and a 21# main spring. Why? B/c that is what my gunsmith, who I trust completely and who knows what he is doing, told me to use. He said I could use either a 16# or 14#, but not to go any lower than a 14#. I asked him about using a 12# spring, and he said that he's seen too many otherwise perfectly running .40s lunch on themselves using a 12# spring and shear their bbls. And my gunsmith is a big proponent of using a shock buff. Link to comment Share on other sites More sharing options...
benos Posted August 6, 2004 Share Posted August 6, 2004 I've shot light springs (11-13 lbs), with and without shok-buffs, for zillions of rounds and have never observed any excess wear whatsoever. be Link to comment Share on other sites More sharing options...

How could that happen from a light recoil spring? I don't see how it is physically possible, please educate me. Link to comment Share on other sites More sharing options...
davidwiz Posted August 6, 2004 Share Posted August 6, 2004 I don't know the specifics. This is what my gunsmith, who has been building championship wining guns for over 10 years, told me. His actual words were, "If you elect to run a 12 make sure you have a pretty heavy hammer spring. Please I would feel better with a 14# spring though." As BE and others have said, they haven't had any problems with running a light <14# recoil spring. I wasn't posting to say I was right or that others were wrong, just what I was using and why. If you email or PM me, I can give you his name. Link to comment Share on other sites More sharing options...
zorba Posted August 7, 2004 Share Posted August 7, 2004 i am now running a 10 lb recoil spring and a 15 lb main so sweet.. Link to comment Share on other sites More sharing options...
LGator Posted August 9, 2004 Author Share Posted August 9, 2004 Ok, got the gun back from my 'smith. He didn't cringe when I told him I run a trimmed 12.5# ISMI spring. He did tell me to keep an eye around the front of the frame rails for cracks, but didn't think that would be a problem. He is not a fan of buffs and from my experiences with them I agree. He did change my mainspring (or hammer spring) to a heavier one. I was running a 16# ISMI. He said he's found a light mainspring can cause erratic primer ignition or FTF's. I think he installed a 19# spring. I don't think his heavier mainspring changed the way the gun runs or the sights track so I'm going to keep it in (for now). -Luther Link to comment Share on other sites More sharing options...
blackdragon Posted August 11, 2004 Share Posted August 11, 2004 Every one has a gun guru, my self included, Mine is Fred Craig now i'm not saying that he gave me this advice, but he did tell me if it works use it if you shoot better use it, I think he was refering to the mental aspect of the game, If you believe it helps you shoot better it will! As with martial arts, after you reach a point, it's all in the brain pan. Later, Ivan SCS Vegas Link to comment Share on other sites More sharing options...
achard Posted August 11, 2004 Share Posted August 11, 2004 I used 13lbs with two shockbuff with no problems. Link to comment Share on other sites More sharing options...
mas Posted August 20, 2004 Share Posted August 20, 2004 what would you guys recommend for a 5" gun chambered in .45 ACP shooting factory loads (Federal American Eagle)?? I'm guessing a buff will be necessary, correct? Can I still drop my spring weights down using factory loads? Link to comment Share on other sites More sharing options...

Dream Posted August 27, 2004 Share Posted August 27, 2004 Seems everyone has a different idea on springs and buffs. My first thought is how the gun feels in your hand. I had one that was beating the frame and slide with a 10lb spring, but you could feel the slide hitting during recoil, so i bumped up to a 12lb and everything runs fine now. So far as what weight spring to use, I think its what feel your looking for when the gun recoils. Just my .02 Link to comment Share on other sites More sharing options...
