you've put your (trigger) finger right on the crux of the "problem." the rohrbaugh is a serious firearm, planned, engineered and executed to produce the best possible results in real-life desperate situations. in such instances, a tap on the finger is a small price to pay for concealability, reliability and firepower.
me? i'm just a dilettante . . . i like the IDEA of the best and most reliable punch in the smallest possible package, but, to be honest, i don't really NEED it, as i'm not on duty, in harm's way, in a particularly dangerous environment, etc. as an "armchair defensive shooter" i can thus afford to sacrifice some firepower for more creature comfort.
in that regard, my R9 is still in personal limbo. from the posts i've read, it seems like a number of shooters here on the forum feel that some grippy surface has improved their control. if my tape keeps my finger from getting bonked, i'm keeping the little guy. as i mentioned above, so far he has functioned flawlessly, and his pointability is unparalleled. if he keeps biting me, i'll have to pass him on to some more serious shooter and go back to my ol' HK4 in .380, which i have shot with pleasure for some 20 years. (do wish he packed more of a punch though).
