I have had "itch" to bubba up (or buy one already done) home shotgun.
I have looked over a couple that I liked. BUT they all had pistol grip (with stock) I found that I could not reach safety on Mossberg at all, and could not set safety on 870s.
One seller suggested I stick trigger finger thru trigger guard and place it on safe// :O
So am I too fussy? I guess I learned with AR to go from safe to fire on target/back to safe/ drop to sling/ transition/back...
Look at a Birdshead grip. Google Shockwave technologies.
Got one on my Mossy. Works just fine.
