rodwhaincamo,the correct answer to your question is yes,no and maybe,it depends. my first thought is,if the problem is truly that you have short hands,then my suggestion would be to find a gun that fits your hand first and foremost.that would solve your problem right there.
if you would prefer to stick with a particular make and model because you like it for some reason,then you have to research into that model and see if there's a solution out there that could possibly work for you but i would say there's no way to be absolutely sure that you would be satisfied after the modification,but you might.i would be real careful with DIY type mods though, and i even hate mentioning those over the internet as you could possibly make a perfectly safe firearm into one that is not.
tommyboy has already mentioned a few that are out there which may be prefered because the solution is more of a produced or "professional" type part that you can buy or have a gunsmith install for you(sometimes even from the very some manufacturer of your firearm as an "up-grade" or a solution they may have already incorporated on their newer models).there are also people who have come up with similar type solutions,like for example,if you do a search for "keltec p11 shortening the trigger travel",you'll find that,and there are a few others aswell but again,i strongly recommend extreme caution(for many make/models the answer may be a flat out no).
however,are you sure that what you want isn't actually simply a shorter reset,that is a different matter.a true DAO trigger is different from one that has a short reset.there are so many different functioning triggers out there now,it can all be very confusing.
for example,the h&k V2(LEM) is basically a DAO "type" trigger but with a short reset.when you chamber a round,you have the "long" trigger pull with a weight of about 7.5-8lbs. when it breaks,the reset is about 1/4 of the way forward compared to the original pull and you can fire again including all subsequent shots. there are other types of triggers out there too and you'll have to find what your looking for.
if you are refering specifically to these new slim type pistols excusively(like pps),then i know exactly what you mean.they all seem to be either true DAO or have a little safety "do-hicky" right on the trigger,like a glock,which i do not like personally.in fact,i am looking for one such beast right now and have found nothing to my satisfaction(other criteria are involved for me though).
there is the bersa bp/cc(or called bp9cc,bp40cc,etc.)which states it will have a "short reset DAO" but i'll have to wait and see if it is actually what i consider a short reset.
in the end,you have to find what works for you but my guess is your problem is actually finding something that fits your hand despite whatever trigger it has.
imo,smooth is more important than the weight,unless excessive which can also be detrimental to control/accuracy, but reaching the trigger so you can use it properly,is also very important.there're many pistols out there that have different back-straps that may give you a solution to reach.
good luck.
by the way,imo,most people don't use their trigger finger correctly.they simply pull the trigger any-which-way.i like to use the correct spot on my finger pad and ark through the second knuckle only,keeping the first joint straight,..but that's for another thread.
