Barney, I looked at a lot of Tristar Kanik 55s at a gun show yesterday. I was really interested in any of the 120 models but only saw the compact100's. For me there were two problems. 1 - the safety was too stiff to operate with my strong had while presenting. From what I read that should break in fairly quickly. A more serious problem for me was that the grip was so big and the DA trigger so far forward that I could barely get my finger tip on the trigger. This was disappointing because I had read a lot of highly favorable stuff about these CZ clones.
What I did buy, but haven't shot as yet, is a SarArms B6 Hawk. All steel version. Grip felt like it was made for me. Comparable to a 1911 but more comfortable. Stiff And long DA trigger, but the best SA trigger I have ever seen on a stock gun. If it is over 4 lbs I would be surprised. This gun looks identical to a 75B but the safety operates in reverse. Up to fire, down to safe. They also make a B6P that is very similar but with a polymer lower, priced maybe a little lower than the TriStar. IMO if you are interested in. CZ75B the Sar B6 will be a lot closer match than the TriStar.
Should get to the range this week and will get back here with hopefully more meaningful comments. Here is a link to the same gun I got at the show. http://www.gunbroker.com/Auction/ViewItem.aspx?Item=334278391#PIC
