10rd Mag extension +3 for 13rds
I was a bit skeptical for the reliability with a stock mag spring. I absolutely was. No issues at all. 200+rds at least or more. No issues at all. Darn fast feeding. Also the question of cost for 3 extra rds. Is it worth it? Really? Well, I think that depends on you. Does the weight of the extension drop that mag freakin fast for a Re-Load? Yup. Damn right it does. Range fun or tactical shooting I’ve had the same results, pretty damn FAST. Is that enough to justify the cost. Well, it was for me. However, everyone has their own comfort zone and training objective. It was the right call for me.
