Default S&W 5" 2.0 9mm vs .40 for supressor useage

I have a bunch of 9mm & .40 semi-autos but very few set up for a suppressor.

I have a few of the older S&W M&P's in a 9, 40, & 45, some with Apex kits.

My current dilemma is I recently handled a friends 5" 2.0 in 9mm & just love the gun.

My problem is I am on the fence between the .40 & 9mm.

I have a very large stash of .40 brass & bullets so a .40 would make sense for me but I want to turn my new (whatever one I get) into a suppressor host so am asking any of the current 5" 2.0 owners how the .40 in that gun is working with a can.

I'm interested in function & noise-- does the 5" 2.0 work OK with a can in .40?

How about function with heavier bullets like 200 grain as I would like to stay subsonic?

I guess I am asking for some guidance on using a 5" 40 with a can in the M&P 2.0?

Can't comment on the suppressor as I don't own one yet but keep one thing in mind...you can get threaded conversion barrels from .40 to 9mm from several different sources. The barrels from the 1.0's work in the 2.0's. Apex has their barrels now which are supposed to be really good. So you could get the .40 now and then later you can grab a new barrel and some 9mm magazines and be good to go.

Thanks for the response. That is a great idea about the .40 into a 9mm. I will need to buy a threaded barrel anyway.

I have a couple of .40 Glocks with both a .40 & 9mm barrel (neither threaded though) & they shoot either caliber just fine.

In fact I can even use the 40 mags with 9mm without issue.

I saw Lenny Magill try 9mm in .40 mags on one of his videos without any issues. I've never tried it in any of my glock conversions but if it works, then why not... obviously not for a defense gun but for a range you I wouldn't have a problem with it as long as it didn't cause a catastrophic malfunfunction.

Definitely check out the apex barrels! I'm thinking about grabbing one of the ported performance center uppers that S&W is selling in .40 and then also getting one of the apex conversion barrels for it. Their barrels aren't ported but I don't care much on a 9mm. .40 is really fun to shoot with a compensator.
