Much if the recoil characteristics are affected by the mainspring. If you need a lighter recoil spring to keep the front sights from dipping (with a 16 or 18.5 pound recoil spring firward battering of the impact areas is a nonissue) you may find ye pistol whips back hard and a buffer won't help much on that respect. So you can use a heavier mainspring (closer to stock 23 pound). This delays unlocking more same as using a square bottom firing pin stop. The firing pin stop, mainspring and recoil spring are all interrelated in this respect. Fit of yhr pistol will effect the actual vslues as well as shooters grip, strength, arm weight and so on. While there are setups which are standard for say a bullseye softball gun, a USPSA major limited gun, stock and open class autos for respective games, the fine tuning comes down to the shooter and the load.
I built a 5" 1911 which fits and nestles in my hand like a glove. Fits my son's hand, too, so he has commandiered it. Anyway, through a basic setup and spring value adjustment we have a recoil spring, firing pin stop and mainspring setup for the 4.2 BE 200 grain load and the same components for ball power loads. If changing the mainspring is an issue, and it can be at the range, fit another mainspring housing for the "loose" mainspring. Then change outs at the range is a no brainer.
