Oh yeah, that makes sense. Didn't think about how buried the mags are with a Vector. Definitely a difference in both looks and handling. I'm not so worried about magazine swapping efficiency with mine, rather the wobbliness of the mags bothered me, so I glued in a thin shim of aluminum and polished it on the front face. My mags fell free on button release as stock, not they need a bit of a pull, and a soft push to insert. Zero wobble which fits my slightly OCD needs. Haven't had opportunity enough shooting mine yet to see any wear on magazine lips... but I suppose that's something to think about. Guess I'll stock up on more 10/15 or 10/17 PMAGs when they're on sale.
