Gonna pick up a second 170. Something could easily happen to the first one and then I’d be screwed. Always good to have a back up. Then I’d have 2 170s anc 2 140s. 

 

I’m also looking at the sps mags for practice. 55 bucks for a 140 that holds 23rds, much like the mbx 140s. Now I’m sure the quality is no where near as good, but then I don’t have to worry about messing up my good ones practicing. But the 170 sps aren’t even worth it? 80 bucks vs 100 for an sti that we know is good quality and will work for many years. But the 140s ars a good deal. I have 2 126s that run reliably though my sps pantera. So if the 9mm are as good as those they should be great practice/backup mags. 

Good luck. Don’t say everyone above didn’t warn you.
