resortboarder Posted October 13, 2016 Share Posted October 13, 2016 I bought a 6" STI Eagle with a 9lb recoil spring and a single alumabuff. Seems really light for a .40 major gun. My alumabuffs in other 170pf guns start to deform after ~300rds and cause issues. I have a friend who uses a polymer buff AND an alumabuff on his 6" eagle and hasn't had any issues yet. Anyone with experience trying this? Does it short-cycle the slide? Cause FTFs in some guns? Link to comment Share on other sites More sharing options...
bokbok_05 Posted October 13, 2016 Share Posted October 13, 2016 I have a 5" Edge that don't run with a shock buff, polymer and alum. Slide was short cycled. Without buff, it runs without problems. The thing is, try it with double shock buffs. It may run with your pistol or not..... Link to comment Share on other sites More sharing options...

Usually the first downside is not being able to slingshot the slide from slide-lock, which isn't an issue in Limited. I may have to just try it, but I only get out during matches and I'd hate to find it doesn't cycle after the buzzer goes off. Thanks. Link to comment Share on other sites More sharing options...
bokbok_05 Posted October 13, 2016 Share Posted October 13, 2016 (edited) Yep. My Edge hates shock buff. Same with me, I only get to try in matches. Didn't have the time for practice sessions. Edited October 13, 2016 by bokbok_05 Link to comment Share on other sites More sharing options...

I ran an alumabuff in front of a shock buff on my 6" SV with a 12# recoil spring with great results. Well, except Brandon griped at me every time I took the gun to the factory......

Aircooled6racer Posted October 13, 2016 Share Posted October 13, 2016 Hello: Use a 5" 1911 12.5lb ISMI recoil spring and no shock buff. Thanks, Eric Link to comment Share on other sites More sharing options...
ParaGunner Posted October 13, 2016 Share Posted October 13, 2016 B. Enos used to run multiple buffs in his pistols. Do a search here on the forum. Link to comment Share on other sites More sharing options...
wgj3 Posted October 13, 2016 Share Posted October 13, 2016 I run an aluminum buff over a polymer buff in my 6" .40. I'm a fan, but I don't tell many people about it because they always tell me it won't work... It also has a tungsten guide rod... It will all likely explode one day.

Sent from my iPhone using Tapatalk I'd never heard about the Cominolli Frame Saver system. Seems unnecessary to have a buffer on the rear side of the flange, but yet not a gimic. I applaud their ability to introduce another design into the market that's not "the worlds first 4 SPRING total recoil reduction system." Link to comment Share on other sites More sharing options...
MrPostman Posted October 13, 2016 Share Posted October 13, 2016 Try 2 poly ones since they compress, that should keep the short stroke issues from happening. The other option would be to have the gun stroked just a tad, which would involve taking some material off of the front of the forward frame rails and bottom of the slide where it hits the frame on the inside at the rear most portion of the stroke. Then you can run 2 shock buffs with no issues. Link to comment Share on other sites More sharing options...
hotrodder Posted October 13, 2016 Share Posted October 13, 2016 I run a polymer and aluminum buff in all my 5" 1911's and 2011's with no issues. I use a 12# variable in my 40 cal guns,9# variable in 9mm, and 13# in 45. All you can do is try them and see if you like it. Link to comment Share on other sites More sharing options...

No problems with it and felt good with an 11# wolf variable.Cominolli is all I use now in non stoke 2011.Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
waktasz Posted October 13, 2016 Share Posted October 13, 2016 10# spring and a square FP stop on my 6" 40 Limited gun. No buffs. What's the buff supposed to do? Save the gun from abuse or make it recoil less? Link to comment Share on other sites More sharing options...
MrPostman Posted October 20, 2016 Share Posted October 20, 2016 They prevent the steel on steel impact at the end of the recoil stroke which in theory should prolong the life of the slide by preventing cracks. They may change how the gun feels under recoil slightly as well. Link to comment Share on other sites More sharing options...
Absocold Posted October 20, 2016 Share Posted October 20, 2016 I run polymer Shok-Buffs in all my guns, some with the Wilson Group Gripper, all with full length rods. Replace them regularly and you won't have any problems. YMMV, some guns don't like having their stroke shortened even that little bit, some need a harder hit to rebound back fully into battery (but I think that's a spring problem, not a shokbuff problem).

jwhittin Posted October 21, 2016 Share Posted October 21, 2016 I'll toss out another option. I use the SpringCo management systems in several of my comp guns. The design makes a lot of sense, they are made in the USA, and it doesn't require any proprietary main springs. Link to comment Share on other sites More sharing options...

DHart Posted November 21, 2016 Share Posted November 21, 2016 With my Edge .40S&W, I'm running the Cominolli (sp?) Frame Saver guide rod with two polymer buffs (one on each side of the base). Flawless performance and makes the cycling feel very soft and easy on the pistol. I love it. Link to comment Share on other sites More sharing options...
