    I looked on the Steyr website and it appears that there is a conversion kit out there for the 9mm to the .40S&W. Does anyone know how much it runs? I picked up (ok, I will pick it up as soon as the 10 day period goes through and I'm back from vacation) a 9mm to round of my collection of different calibers (already had .45 and .40 in XD's and I wanted a fairly inexpensive range gun and alternate carry). Anyways for range I think I'd use the 9mm barrell but if I could convert it to .40 for carry that'd be great!

    do you have a link to where it says that?

    I doubt you can go from 9mm to .40 without changing the while slide.

    You are changing the whole slide. Look here at the kit. It's the whole slide and barrel and the barrel says .40 on it.

    May I ask what was the price on that kit? On SteyrArms site in Cummings, GA it has accessaries, but the kit is not listed.

    I really wished they would list prices.

    I talked to one of the head guys out in Georgia a couple of months ago about the conversion kits; 40 to 357; and he informed me that the kits were discontinued. He said for the price of the conversion you could almost buy the complete gun.

    Better to get the 40SW and convert it to the 9MM. Not sure it'll work the other way 'round. IGB has the 9MM barrels for convertin' from the M40/M357's. Talk to Marc at MDW first.

    Good luck with it.

    40 to 9?

    Is converting down as easy as swapping barrels? Is the 40's spring too beefy to avoid a stovepipe if a 9 barrel were dropped in? Kinda curious....if that's the case tell me where I can find a new M9 barrel.

    barrels dont interchange for 9 to 40sw/357sig

    you would need the 9mm slide. 9mm barrel is very poor fit in the 40/357 slide.

    IGB has conversion barrels.

    kits IIRC ran $200-$300

    dont know the spring weights for m9 and m40 mainspring

    Conversion from 40 to 357 (conversely 357 to 40) should be a change of barrel only. I believe Steyr M/S A1 series are designed just like Sig 40's and 357. You simply switch barrels (in same model). Spring tension should come into play depending on ammo (if you reload - make sure it's strong enough to cycle the slide.) Although there are no after market barrels for Steyr M/S A1 being made locally (there is one made in Austria I think that was posted awhile back) that I know of , It's just a matter of time and we will see those local barrel maker's like Bar-Sto etc. will start making it. I hope there would be enough demand soon. Switching from a 9 to 40/357 is a whole lot different because of many factors notably ballistics and ammo size/shape - need to change mags, ejector, extractor, slide etc. and of course barrel - It's not practical.
