You have to buy a .050 gauge bar too, but it is worth switching.

Here is their ps3 chain, I haven't tried it yet.

You can get 0.050 picco in
PM and PS with no safety bumpers. Either one cuts well.
What gauge is your bar? It will be stamped on it.
I'm not sure if there is 0.043 gauge non-safety chain?

Here is the catalog...
I am happy with 3/8 pico micro semi chisel non safety chain in 043 on my 180s at 16", they work well, easy to sharpen too.
I don’t mind the “3” chains. The little humps next to the raker don’t even get in the way like that shark fin in between the cutters crap Oregon has.

The "3" just stands for 1.3,
or .050 gauge.
or .050 gauge.
My ms170 came with a 16” bar with the 3/8 .043 chain!
I took HarleyT’s suggestion and put a 14” bar with the little thicker 3/8 .050 gauge chain!
It cuts great with it!
I’ve only cut about two good truck loads with it, since I switched, mainly Hickory, but cuts very well! (BUT: I did put the ms250 carb on the 170 so it would have a fully adjustable carb on it, plus a muffler mod)
I haven’t cut long enough with it to tell the overall advantage of that chain over the .043, but it pulls the .050 no problem!
Another tip about the ms170, is that the ms210-ms250 “side chain tensioner” will fit perfectly in the 170, making it easier to tighten or loosen the chain!

I meant 3 as in RS3, RM3,PS3,etc. The green chains.

Oh OK...
You want the bar with the correct groove width so that the chain is not too tight or too loose! (Wobbly)
BUT you can find combos of bar and chain for $20 and under!
I think I got the 14” bar and .050 chain at TSC for $19 something?!
If I can find it I’ll post the link to some other brands that someone posted on another thread about this!
No 0.325 is different sprocket pitch than 3/8 picco or normal 3/8 (which are themselves different). And most 0.325 is 0.063 groove so would not fit bar groove either.
Both pitch on chain/sprockets need to match, as well as bar groove width.

Rule of thumb: 40cc and under- 3/8 picco. 40-60cc - .325. 60cc and over - 3/8. .404 we'll leave alone. Its got some wiggle room, but I pretty much adhere to it.
It really doesnt matter the gauge, personal preference or cutting needs.
I like the 61pmm3 chain that I assume the guy in post 1 does not like. Perhaps he is using brand x not Stihl. It is reduced kickback green chain used on green 7 tooth nosed bars. It has bumper drive links (at least in this market USA) and seems called safety chain by most folks.
