I have one of each, a Glock 36 and a Colt Defender. They are almost identical in size and weight. The Defender holds 7 and 1 and the Glock 6 and 1. I have Pearce Plus Ones for the Glock but I don't like them. They make the Glock bigger than the Colt and harder to conceal.
I notice that nobody has mentioned the Springfield Micro Compact. It's fairly new on the market. It's quite small and light, but the recoil is no worse than my much heavier Springfield TRP because of the recoil spring design. It's not cheap, but it's very accurate and a great shooter.
