Take the one that gives you the edge in competition. Keep practicing with both.
I was told by many people that I'd never be able to shoot well with a DA/SA gun and that I needed DAO, especially because I'm a girl.
Not only did I prove them wrong, I can out shoot them regularly! I don't find DA/SA or HK's in general any slower in actual firing than a Glock.
Speed wise, I'm just as fast shooting a HK as I am a Glock but far more accurate.
Does this mean the HK is more inherently accurate than a Glock? I wouldn't say so but I will say it means that I shoot the HK better!
Diesel pickup, lift kit, 10mm, loud exhaust, big dog.... You didn't get enough attention as kid did you?
