Second, the mag catch spring was designed around the 20 round mag, and even the 30 round mag is half again the weight on the catch and spring. Using coupled 30’s, thats 3x the weight on the catch and spring.
Yeah it’s a close range ordeal. The balance isn’t an issue for my usage. Intermediate to long range definitely don’t want it. I like them for vehicle security work. It’s hard to get to pouches and stuff in positions behind wheels and working under the vehicle and such.
I also use them for the bump in the night one because I’ve no way to carry extra in my sleeping attire.
