I totally agree. I had a similar ammo issue using 115gr Blazer Brass, in a Walther CCP M2 9mm pistol. That Pistol grip felt so good in my hand, that at one point I considered it for a potential EDC. Scouring forums, I found that in this case it was a firearms issue and not specifically ammo related. Turns out this pistol is sensitive to the ammo it likes to eat. Blazer Brass happens to be one it doesn't like (among others).
So, much the same way you question this ammo with being able to firing reliably in a defensive situation, I too can't rely on the CCP M2 as a EDC.
