Hi Firebreather. Your questions are good ones. I do think the Rohrbaugh is worth considering if you have a use for a small, powerful pocket pistol. The recoil, while stiff, shouldn't give you any trouble at all, since you're an experienced shooter. It would really be ideal if you could handle, and even dry fire one, before deciding, but most of us didn't do that either before ours arrived.
My Rohrbaugh has fired every piece of 9mm I've put into it, without a single bobble. I do keep the piece clean, and I do use quality standard 9mm factory ammo. If you do the same, odds are very good your experience will match mine. If for some reason it doesn't, the Rohrbaugh folks are VERY interested in correcting any problems that may occur in their products.
If you do get a Rohrbaugh, the trigger may take some getting used to. It is a very smooth but long squeeze, and since the pistol is so tiny, there is only a fairly short distance between the backstrap and the trigger when it reaches the position for firing. I'd just be guessing if I said this could be a problem for you, because I only have medium sized hands, but it would be great to have some forum members with huge hands chime in on this, because I'm curious about it myself. Is it awkward for you big-handed folks to reach the point where the tigger fires, and does having huge hands allow the pistol to rotate or move in your hands after firing, so you have to readjust your grip for follow-up shots?
Once the trigger has fired the piece, there is a fairly long forward stroke needed to reset the trigger for the next shot. Double-taps or triple-taps are not as rapid for me with this pistol as they are from autos with shorter resets. It's more like Bam, Bam, rather than BamBam.
I'm in no way dissatisfied with my Rohrbaugh, It's a superb, powerful, beautifuly made, special niche tiny pistol. I like it a lot, and having sent hundreds of rounds through it now, I would personally jump at the chance to own it if I didn't already have one.
