I'm going to guess you will not find much if any .45 solvent traps threaded at 1/2-28. That would make for a very thin wall on the end of the barrel. .578x28 is a more standard size thread for .45 ACP. As for who, couldn't tell you, I haven't looked into solvent traps myself. Of course I might be wrong, if so I will be corrected soon enough.

As Camocorvette said, you need a booster to get a suppressor to cycle a pistol. A direct thread suppressor with no booster will not cycle a semi-auto pistol. The use of the booster assembly allows pistols to properly cycle when the weight of a suppressor is added to the end of the barrel. Most pistols with a browning type action (Glock, Sig Sauer, HK and etc.) will require a booster to properly cycle.
Look at the JK Armament. Every piece screws together so you can get different end caps and adapters as well as add and remove baffles as long as you don't do more than what you put on your form 1
You can swap between booster, and dt mount. Maybe use a brake/tri lug on the PCC to eat up some of the space the booster used to occupy. If you buy an "ASR" type tube, you will not need to change spacers in the proximal end when you do so; as there is a machined in shelf/blast chamber spacer machined into the tube
