I've not had a problem with my Rohm Sport, particularly at 20 yards or below. I've had the power upped fractionally just to be on the safe side.
I'm happy that it will drop all but the most stubborn knock down over at 30 and even 40 yards now. Shooting from a bench I hasten to add. The knock up, knock down resettable targets can occasionally pose a problem. However, I've seen them cause the odd problem for an underpowered rifle if they aren't hit in the right place at the right angle.
Does (or should I say did) FT pistol and HFT pistol just fine for me.
