I own one and carry it always. Mine's a 1st-generation model without thumbrests, finger grooves, or tactical rail.
I use in all 4 of my magazines Pierce extenders that make the grip tall enough for all my fingers, and I've filed a little bit of material from the entrance to the triggerguard, visible in this pic...
...so that it fits my hand a little better.
I've developed high-performance PD reloads with the excellent Hornady 155g. XTP, and I practice often with those full-power loads.
The more I shoot it, the more I like it.
BTW, if the grip angle of the Glock pistols is different than that of most 1911s, maybe that's why I don't much like the fit of 1911s. My 23 and 35 fit me VERY well, and I manage to shoot them well, too.
