Looking to buy a sub compact 10mm

Don't think so...

Based on the how thoroughly you asked your question I have to agree with Ridgerunner.  It is not that you can't get away with it but an OEM G29 (only small 10mm I have experience with) with full power Underwood ammo was more than I could fully control. A lot more.

But let's reverse engineer the question.  What if you want to shoot a sub compact 10mm handgun that launches a 200gr WFN hard cast bullet at slightly over 1,200 fps with good control and accuracy?  Easy peasy.  There are a few ways to do it.  I have a G29 with the aftermarket 21# Wolff spring set, 4.5" Storm Lake barrel and +0 Pearce grip extension.  There are few critters that would not be slapped down hard with this setup.

The Glock 29 is too 'chunky' for my tastes. I prefer the Witness Compact polymer in 10MM. 1" across the slide, and 12 round capacity.

EAA website says it's 1.4" wide. Is the slide only 1" across?
I'd like to get one someday.

Yes, just 1"

BTW, my Witness polymer compact has been totally reliable since the mods, even with Underwood ammo. Not sure how long it will last with a steady load of that stuff, but it's good to know it'll handle it. There are other offerings out there not quite up to the Underwood level, but plenty potent and perhaps help extend the life of the gun.

Steel Witness Compact is another option. I don't know what changes they have made to it, but at least one ammo maker got his to run 100%.
