Recoil rod centering bushing will solve the problem.
If anyone is interested I bought the EWK wrench thinking it may work with the SiCo t hread adapter since it has similar notches to the OEM protector, it does NOT work with the SiCo adapter, bummer.
I need that adapter, unless someone can make a damn tool to take the SiCo adapter on and off with ease.

So I was in the local LGS fondling a G43 today (mine arrives at another dealer tomorrow) and I noticed they had a M&P 22 compact with thead adapter on it, store owner said it came that way from the factory. Sure as shit, I see Smith released a “suppressor ready” model just before NRA show that comes with an OEM thread adapter AND WRENCH. Does anyone know where to obtain the suppressor kit listed in the above press release?
