I think the can is too heavy, any help with this issue? Different recoil spring? Found other firearms and they have changed the recoil spring but the XDM 3.8 has a combo spring and I can't find anyone that sells this type.
I'm not sure it's too heavy as there isn't much weight difference between the tirant 45 & 9, i think it has more to do with not enough back pressure with the large 45 cal hole in the suppressor when using subs. The tirant 45 sometimes has trouble cycling correctly on my XD9 service when using subs, same on the glock 17. You will usually get better results when using hotter ammo, although it will obviously be a lot louder. Try it with some 115's and a few cc's of water.
