adding paddle mag release to a RAW SP89

[tonelar]

I've finally got the parts to do it, but the work isn't cheap... should I leave it stock or go for a paddle magazine release?

I'd have the paddle release added.

If you're going to send it away, might as well have the MP5K threaded barrel with 3-lug thread protector installed since it's a RAW.

Might as well throw an FA carrier in it while it's there.

TSC Machine can do the work competently:
