I agree on the No Rail preference.
Here's what Wikipedia has to say about the PT-92:
"Decocker. . . this feature was added to the second-generation models in the early-1990s, which also included the three-dot sights found on the Beretta 92F. A third revision in the late-90s changed the grip and slide design (which now has fewer grooves in the rear). More recently (as of 2005), Taurus has begun manufacturing the PT92 with built-in accessory rails on the frame, a feature found on the Heckler & Koch USP and third generation Glock pistols.
