Hello Cody, you can, but it would need to have a threaded barrel. budsgunshop.com/search.php/q/threaded+barrel+1911 hope this helps!

Yes, you surely can.

Good evening to you!! Yes you can put a suppressor on a 1911 45 acp or 10mm as long as you have threaded barrels. Hope this helps. Have a good rest of your day.

You can, as long as the model has a Threaded barrel. As mentioned, most 1911's do no come stock with a threaded barrel so you'd need to acquire one.

Hello Cody. You can get suppressors for either caliber, however note that most m1911s do not come with threaded barrels. If it does not come with the threaded barrel you will have to add one aftermarket.
