The problem that made me start this post is now solved.

I got a leather slip on pad from Pachmayr, it has a new super soft decelerator material inside, and it really eliminates that sharp felling from recoil when shooting with light clothes from the bench.

Even better, the LOP with the slip on pad is perfect for shooting with light clothes, and when the cold comes and I use heavier clothes I just take it off.

Thank you for your answers.
