BudsGunShop.com - 9mm instead of .45

the GSG kit is currently out of production normally the conversion kit will work on any caliber 1911 (my AA kit is on 9mm 1911 right now) but I suggest contacting ATI and asking 800-290-0065 the Advantage arms conversion kit for the commander is here budsgunshop.com/catalog/product_info.php/products_id/714000162/ADV+ARMS+CONV+KIT+CMMDR+1911+22LR />and link to the Advantage arms page advantagearms.com/mm5/merchant.mvc?Screen=CTGY&Store_Code=AASOS&Category_Code=1911

I have 9 mm guns from 4 different manufacturers and NONE of them have ramped barrels now all of my 40 cal 1911s do have ramped barrels I need to try mu AA conversion kit on my 2 40 cal 1911s and see if it works on them I know my AA kit works on all of my 9mm all of my .45acps (except the officers) and it also works on my 38 super 1911 the barrel on the Advantage arms conversion kit is a ramped barrel so it does not matter if the frame has a ramp or not

Nope Shaun. Most 9mm 1911's have a ramped barrel and will not work with the conversion kits as they are made for guns with the ramp in the frame. For another 1/3rd the cost of these 22LR kits(which usually require tweaking to make reliable), you can likely get an almost exact 1911 in 22 caliber from GSG, Sig Sauer and ATI than buying the conversion set and likely not have near as many headaches as well.

Goood question. If it only says 45 then I would say not to the 9mm. It is possible it will work but I’m not going to lie and say it will. You should call ATI.

It should work. The only difference in the frames is the ramp and the 22 feeds from the magazine so it's not used.

No it will not work.
