A question for buff experts...
It seems to my amateur mind that there are three issues to resolve in the use of shock-buffs in 1911 pistols:
1. The installation of a buffer reduces the lenght of travel of the slide by slightly less than the uninstalled width of the buffer. That is to say, the slide will stop around .08" short of fully retracted, because it simply can't go back any further due to the recoil system being fully compressed earlier due to the buffer's width. This could be an issue, I suppose, with extended extractors and rounds with a very long over-all length - it amy also effect slide stop operation in some cases.
2. Slide velocity returning to battery will be lower. This is because the collision between parts has been made more 'elastic" than the previous nearly 'inelastic" calnging of parts - or to look at it another way, some of the energy that otherwise would 'bounce" the slide back into battery is now lost compressing the shock buff.
3. The possibility of disabling a carry piece with fragments of a disintegrated buff. Myself, I will have a buff in my carry piece - I tear mine down often enough that I don't think the risk is that great,
Keeping these three issues in mind - if one wants to run a shock buff, (ESPECIALLY in a carry piece), why NOT do the following mods?
1. Modify the guide rod by chucking in a lathe and facing off enough material from the recoil spring face and the other face to account for the thickness of the buff. If the full thickness can't be so accounted for, a modest trimming of the recoil spring itself should restore full travel to the slide without a noticible change in function - I should think at most one coil would have to be cut, (depending on wire size...)
2. Run a heavier recoil spring, to assist the return to battery issue. This might require going to the larger radius on the bottom of the firing pin stop on those guns that have the small radius.
3. Run a buff thats on the harder side, closer to nylon, rather than the soft gel kind - this will help both with the slide velocity and the fragment issue.
4. Lastly, and most important - why doesn't someone make a shock buff with the plastic inside a buff-shaped mild steel or brass cup, with a soft metal plate bonded to the other side? That way the buffer material is conpletley captive, and with modern adhesives, it should not only last longer, resist gun oils and solvents better, AND pose no risk of tieing up the action even if it fails - it wouldjust become an inert "shim" in the recoil system. You could call it the "Carry Buff" - and market it with the modified guide rod.
Thoughts?
