I got mine in the mail the night before leaving for vacation, so I haven't messed with it much. My intent for is is to be a lower profile battle belt so i'd like to be able to reinsert a fresh mag or a coming off a reload with retention. I went ahead and grabbed some fastmags for the rifle but haven't settled on the pistol yet. I really like the 10-sped stuff but you're right they're really tough to insert one-handed especially if you aren't looking directly at it.
