IF my SD/recreational gun had to be a CZ, it would be an SA in 40... for many of the reasons cited by Walküre.
I have an SP-01 and actually have it listed on my CCW. I tried carrying it ONCE. The dang thing is pretty heavy (41.6 ounces unloaded, not sure how much it weighs with a full mag). I much prefer to CCW a lighter gun.
My personal choice for everyday CCW/SD gun is a Glock 22. Cheap enough that if it gets confiscated after a lawful SD shooting, I won't cry. Very reliable and accurate. Light weight. Accessories (e.g. holsters, mag pouches, sights, etc.) are easy to find and affordable. Easy to maintain. 40 cal ammo and components are cheaper than 45, which is a bonus. Tolerable ergonomics... I used to hate the weird grip angle and "2x4" feel but I got used to the gun pretty quickly. Now it is one of my favorite guns.
You mentioned SIGs... well, here is my SIG story:
I am a former SIG owner... Loved the ergonomics, accuracy and build quality. In the late 90's, I attended a 4-day handgun class with my P229... it worked well and I hit everything I needed to hit... but one of the instructors let me shoot a course of fire with his 1911, "just to try it out." WOW. With that borrowed 1911 and basic familiarization in its operating system, I was noticably faster and more accurate than I was with my SIG. I realized then that the 1911 is a holy relic imbued with the spirit of Saint John Moses Browning, while the SIGs were just nice handguns. Shortly after that class, I sold both SIGs to by a 1911 (EDITED TO ADD: I also had a P220 at the time). I have no regrets about that decision, and still have that 1911 to this day.
I forgot to mention that during that class, I saw a guy (who claimed to be an experienced police officer with 13+ years on the beat) shoot himself in the leg (with his SIG) because he got sloppy and holstered his gun while still cocked. He touched the trigger during the draw and negligently discharged it before he cleared his holster... the 180 grain 40 cal bullet went THROUGH his holster, THROUGH his thigh, THROUGH his knee, and lodged into his calf. Yeah, I know it was operator error and the gun was not at fault... but ever since that day I have been none too thrilled with SIGs.
