40sw mags

[Cowguy]

Are there any suggestions on which 10mm mags to get for a 40 cal single stack? It will be for uspsa and steel challenge shooting.

Wilson Combat 47NX are the 10mm mags that I use most for 40 cal Single Stack: https://shopwilsoncombat.com/MAGAZINE-1911-10MM-FULL-SIZE-9-ROUND-STANDARD-BASE-PAD/productinfo/47NX/

Will they work with a magwell?

They work with the Dawson Ice gap magwell with either Dawson's Ice insert or Shooting Sports Innovations' "Bottom Feeder" inserts.

I use Tripp 10mm mags, they also work with the Dawson magwell.

I concur! The Tripp Research 10mm 10-round "System" mags work well and are designed to fit in the USPSA box to keep your gear legal.

 

When my Wilson Combat factory springs and/or followers wear out, I replace them with Tripp's "Super Special Upgrade Kit" (Springs: 15C.042, Follower: FOL-FLX-10mm). You have to seat them with a little authority, but they eject with authority and that's my goal.  On some mags, I have to trim about one coil off of the spring if it binds with 9 rounds (to use the mag as a backup when shooting Single Stack minor or L10).

 

FYI, I always had issues with the 9mm Tripp mags due to the top round sliding forward and hanging up on the frame due to the low skirt cut on the top-front of the mag, but don't have those issues with the 10mm mags and SWC bullets.  That said, if some 40 S&W bullets with a more pointed profile do hang up, it wouldn't be a real problem for Steel Challenge as reloads aren't done on the clock but could cost some time in USPSA.

I went with Tripp 10 rounder and couldn't be happier. They have worked perfectly so far in a Dan Wesson from CZ Custom.
