Norrell's molycoat can make stainless look very close to parkerizing, and you won't need to strip the entire piece down to bare metal either. I use brownell's 909 to degrease.

It goes on very thin with an airbrush. You can tweak the color to get the shade you like - use the colt gray for something that looks close to a zinc phosphate, mix this 50/50 or so with the flat black to get close to a manganese phosphate, and more black to get darker. If all you're after is the ground off weld at the magazine cutoff, It would not be hard to hit that one area and make it pass the 5 foot stare test.

I believe it contains an acid solution. I've used it with good effect to "touch up" parkerizing on conventional steel firearms. Also- they claim it will blacken SST as well.
