Simple question, at least I think it is. Does anyone know if factory 180gr 10mm will fit in a Wilson ETM?

On Brian's main page, he lists fitment as .45, .40, and .357sig ... but if you click through the "more info" link, it lists .45, .40, and 10mm.

Inquiring minds want to know =)

A factory 10 will fit in a 10mm single column magazine, but not in a 40S&W single column magazine. The 40S&W mag has a spacer in the rear, because a factory 40S&W round is too short for the 1911 design, thus the spacer. The same thing applies to 38 super vs 9mm.

I get that, but my question was whether using Wilson ETMs (which are made for .45 ACP) will work in a 10mm gun. Interestingly, Wilson's own 47NX (their .40 specific mag) doesn't have the spacer at the rear.

Brian had told me over the phone that Wilson ETMs work great in a .40 (he neglected to mention that that's only true if you load them to a greater OAL, which isn't possible in my case since I don't reload) so I bought 3. The gun I had originally bought them for is on its way back to the manufacturer to get the barrel reamed for 10mm (long story) and I'd like to know if I can use these ETMs as 10mm mags.

It should work. I don't have any ETM's here, but I just loaded some factory 10mm 180gr FMJ ammo into a Wilson 47D and they fit fine....that same mag works fine in a .40SS gun with .40 long as well. R,

If you don't have a .45 and need the ETMs for that just buy the 10mm wilsons.

I would, but I'm sitting here with the ETMs on the desk next to me right now. I could go and lose some cash reselling them, but before I did that I'd like to see if they'll work.

I have neither the gun (on its way to the manufacturer as I write this) nor any 10mm ammo, so you guys are my best source of info =)

Only one way to find out. I know my .40s don't like .45 mags. I know a lot of people who use .45 mags to run .40s though. In any case don't settle on a mag just because you have a bunch of them. If they don't work in your gun try another brand. Nothing kills a SS score like mags that a gun doesn't like. Now its not to say the mags are bad, or the gun is bad, just that the 2 don't work well together for some reason.

Try to stick them in the mag and see. On the ParaOrdnance .40 S&W mags 10 mm rounds will got in them with no problems whatsoever.

They will most likely work fine (mine do) but, if not, you might need to squeeze the lips together slighly to make them work.
