35 & 40 degree locking blocks user reviews

Currently running 40* in my SP9a3 w/ omega 9k and hub ss buffer it is almost on par felt recoil as my mp5k w/ same suppressor.

Tried my B&T Vers36 for low back pressure but not much difference. Seemed better on the Kuna for felt recoil and helping to keep the gun slightly cleaner.

Order arriving Saturday for a 35 for SP9A3 and a 35* &40* for my SP45A3 w Mojave 45.

I’m anxious to hear others experience with these new locking blocks especially for the SP45A3 users?
