[ No , l don't own a Hellcat , but nothing against them . Would have been perfectly viable option . Trigger typical of class , good to have option of thumb safety , and like the OEM sights .
But experience with the OG Micro Nine , its refined cousin , and just now a G43 ( no X) . But my pontificating addresses the Micro guns as a class . ]
What do you consider the role of a Micro gun ?
* To Me * , it's a binary choice . Is it for normal cut pants pocket or ankle carry ? Then the over ridding criteria is Minimum possible size . Even if compromises shootability . The goal there is " good enough to be useful for intended purpose " .
Way back when with the OG Micro , my conclusion was that it could do at 15yds , what normal pistol could do at 25yds . ( Insert comparison of Airweight J frame vs K Frame equivalent) Aka , still useful for BUG / deep concealment , for a lot / many / most ? Situations.
In the gun world there was trend of " regular " pistols having sequentially smaller variations . Now it's flipped upside down with starting point of pretty much as small as semi practical, sequentially having larger and larger variants , with the kitchen sink hanging from them . Until the two trends overlap in the middle.
Is that a bad thing ? Nah , options are good . I just look in amusement, as everything reverts to essentially the same form factor , that is objectively and ergonomicly a sweet spot .
