Nothing comes close unfortunately. I like glocks but they are just not up to the job.
the other Tm pistols may outperform the hicapa in certain parameters but for competition use they just can't keep up.
i don't use a hi capa for skirmishing for many reasons but for comp shooting you would be disadvantaging yourself by using anything else.
at the European champs this year one guy did well with a glock in standard division but that was the exception, and whist there were a couple of guys with Cz shadows most end up with a Tm based hi capa.
I moved from a glock, there is a grip angle/ trigger relative to a hicapa to consider,also glocks are more temperamental.
Tm hk 45 looks like a reasonable design double/single action so potential for a better trigger than a glock But my reasoning would be what would you be gaining by using one over a hicapa
the big issue is do you wish to to progress competing, if you do and move through the classes a platform that is effectively identical but has more bells and whistles to speed you up is a more sensible approach than changing platforms
you may not think it matters and at the lower levels it doesn't, when you get beaten by tenth of a second for no other reason that you are having to change your draw to accommodate a change in grip angle because you used your glock instead of your hicapa then it starts to become annoying.
(It's probably more than a tenth or two but a delay is a delay)
