da shotcaller,
Check.
The ONLY differences regarding PSD to Pistol configuration is the proprietary Gunsmoke Ind. Recoil hardware on receiver that LWRC uses.
6.8 SPC pistol uses same recoil components as the 5.56 mm pistol.
Regarding the recoil, my opinion & tactile perception is this. It feels similar to a 5.56 mm recoil w/ a slight umph w/ a fairly intense blast impulse
Definetly less than my Noveske N6's which are to me very manageable.
There are several different ways to mount and shoot it.
There is an SAS method used on the MP5's using sling tension that works fairly well if you practice it.
There is a cheek weld method that works well. Make sure to exhale as you breath, clinch your jawline and relax.
An IPSC style pistol shooting method that works OK, but not my favorite for accuracy and distances beyond 50 yds or so.
