I thought about posting this but, didn't want to rain on Glock's idea. Since you have, I will wholly agree.
Early in, I too tried this to up my shell count. Post quickly learning that carrying the rounds forward was a problem, I turned the sling and carried them aft. Having the rounds swinging at the butt helped. However, the problem remained, a weight / pendulum issue.
B Coyote recommends the mini sneaky. I went this route several years ago for rife mag and shell carry... goes well in the trunk, grab and get. I've never looked back.
