Sidearms & Scatterguns 10mm help subsonic

Before you say just get a 40 45 9
Read the post.

Helping a friend who wants a do all pistol. What he wants to do.

1.Home defense subsonic and a can.

2. Take backpacking/ fishing in bear county.

We can find lots of great factory ammo for bear defense/ outside use. Not finding much on subsonic.
Winchester and hornady use to make some subsonic.
Anyone know of anything being made now? Speer is 1100 so maybe.

Thanks

last time I checked, most 200gr rounds are chronographed out of longer barrels (5 +"), and many are pretty optimistic. Something like a, G20 should be under the supersonic threshold (barely) with the Speer Gold Dots.

He's not wanting the same bullet for everything, is he? A personal defense load is not a good bear load if the bears are of any size. Something designed for IWB/FBI penetration is just getting started when it comes to what you want for old griz'.

Did he buy a pistol yet?

The 10 is a great round, but if you are wanting subsonic....you’re barking up the wrong tree. If i wanted a do it all.....and suppressed was on the requirement list....i’d be looking at 45 super; and just shoot 45 acp through it for the suppressed work.

If he already bought the gun and is married to it, then handloading is the only way he is going to get there. And i’d advise loading as heavy a bullet as possible to take up powder space and to deliver more energy on target.

myronman3, is right it's possible to load 180gr. and up, to subsonic velocities, but finding something that'll work for self-defense in the 10 is going to be non-existent (in a factory load). Plus, you may run into cycling issues as well, don't know for sure as I've never loaded any sub-sonics for my 10s. I don't think the 10mm was ever intended to be a good sub-sonic round. It'll certainly do both the jobs he wants it to, just gets more complicated if he has to have subs.

More guns=more better. Why try to flex one to do everything. Glocks are fairly cheap, so buy them in bulk.

You should be able to buy a 10mm glock and shoot 40 S&W with a slide swap.

You can shoot 40 in a 10mm Glock using the extractor for headspace.
