OK, hit the range today and put a few rounds down for comparison. Not a lot of shooting (only 50rnds per pistol), but shot in 5rnd groups (shoot 5, switch pistols, shoot 5, switch, etc) at various ranges from 4yrds to 25yrds. So, here's the updated notes...
T120:
--it was shooting low & left (need some sight adjustment, didn't bring my tools)
--didn't really care for it, it felt like a toy. Recoil was easily manageable even with the light weight, that wasn't the issue...it just didn't "feel" right. It had no malfunctions, no misfeeds, no problems whatsoever, just a personal preference.
--it was not as accurate as the other 2 pistols (P120, SP01), nearly double the grouping sizes of the P120 at distances at/over 15yrds.
--overall, decent pistol but not my cup of tea. It'll be a range gun for my oldest son.
P120:
--after shooting it and the SP01 side by side, it is a good substitute if you cannot afford the SP01 or can't find one. My original assessments were a little off once I had both pistols in hand and firing on the range. The weights are different, but not by much. Thinking back on things, the machining was probably better than my SP01 when it was brand new (the SP01 has over 15000rnds through it, I've cleaned up/polished all the surfaces that needed it, and it's well broken in). Only someone intimate with shooting a SP01 will notice the slight differences in the performance (not lock times or anything like that, but the more objective feel).
--the trigger on it was still better than the T120 and probably was better than my SP01 when it was brand new.
--I consistently grouped well. At 25yrds, I was getting 3-3.5in groups from it (by comparison, my SP01 groups at 2-2.5in at 25yrds; the T120 was 5-5.5in), at 4yrds is was second nature/mechanical to put the rounds through the bullseye and make one sloppy hole (this was my last string shot with all the pistols, 10rnds total) without much effort, all shot freestyle...the same happened at 7yrds, one sloppy hole.
--while I'd prefer ambi safeties, this one is acceptable and easy to manipulate. The sights at first seemed small and rather pedestrian, but they were easy to pick up in a dimly lit indoor range.
--again, this pistol didn't have a single hiccup, malfunction, problem at all. It did feel more natural, I was able to recover quickly for a follow up shot, and it just felt right (perhaps mostly due to my love for the SP01).
I won't talk about the SP01 other than the comparisons, it wouldn't be fair as it is tuned and well broken in. Overall though, while the P120 is not a SP01, it is a very good clone (though I'd prefer a heavier barrel similar to the SP01's). For now, the SP01 will go into the safe while I beat on the P120 and see how it holds up. I'll be using it for running drills, running it hard and mercilessly, to see just how good it is and how well it holds up compared to the SP01. I'll give it to 1000rnds before I start to tinker with it, but so far I like it and can't wait until it's time to start tweaking it.
BTW, to the OP...mine was $382.11 from Grabagun with free shipping, then a $20 transfer fee for my FFL. I didn't have a good experience with Grabagun, but that's a whole different story (took a few days shy of a month to get the gun...which was in stock).
