I just bought an SP5 and want to buy a suppressor that 1 doesn't blow back too much gas and 2 can be purchased in Europe. I tried an AU ASE Ultra from Finland and there was a lot of blow back it was quite though. Any suggestions??? I am also thinking of putting an Aimpoint Duty RDS MR on her and was wondering would the 30m be high enough or do I need the 39m to cheer the front sight?
