The TiRant is user serviceable and the Osprey isn't. Yes, it is nice to be able to use your regular sights but I have an issue if I can't take it apart for cleaning.I'm not sure what you mean by standard as there is really no such thing. The Seals use KAC suppressors for their HK's. I would recommend the two mentioned above: Silencerco Osprey or AAC TiRant, with a slight favor in .45 towards the Osprey.
That's definitely a personal preference, as you know in .45 it's not necessary. Both cans are great, I was between these two and for me it came down to what my local dealer had in stock... a TiRant.The TiRant is user serviceable and the Osprey isn't.

I presume you mean, for hosts other than the Mk23 or Tactical? I have the Mk23 suppressor and a booster for the Tactical. One suppressor, two guns.I almost bought a knights, that was until I realized you can't get different boosters for different hosts. Salty as it is, I don't wanna be tied to one caliber even if it's the only one I plan on running it on.
