I've never picked up a genuine Hi Power, what do you like about them over a CZ or other HP clone?
The grip is smaller in length and fits smaller hands better (IMO), the safety is in a poor position on CZ if you are really used to 1911 safeties (again, my opinion and hand fit). The 75s SA trigger will be lighter and better than most stock BHP, even with the mag safety removed (which really helps lighten the BHP trigher).
I have XL hands and find the Hi Power and better
feeling gun in my hands, but my high grip and hand size leads to slide bite almost every time I shoot my Hi Power, the CZ beavertail eliminates this but is in a less comfortable position than a extended beavertail 1911.
I've spent years trying to find the correct 9mm, double stack, 1911 trigger (or close enough) SAO gun and the closest I was able to find was the SIG Legion 226 SAO. The beavertail, undercut trigger guard and flat trigger really set it apart from standard Sigs, for me.
The high power bit me and trigger isnt all that nice (though I like mine), CZs can be really nice in the trigger but I dislike their thumb safety and the grip doesnt fit me just right, the rest usually dont have the right trigger for me, doublestack 1911s are just a bit too bulky for carry (again, I like mine) and the EDC X9 is about $2K too expensive for me. I'm picky, I'll admit but it's been a long search to try to find a 9mm hi cap replacement to my excellent VBob
If you can live with the safety location (important for SAO) the CZ line is a great place to start, or one of the myriad clones.
