Alright, since I'm new to the forum too I figured I better get in a bit of board time. I own this firearm and have been concealing it for over a year now. I carry it in a smart carry holster every day.
On an issue of size, I carry all the time on campus and in all sorts of physical situations. I like using a smart carry hoslter because of its deep concealment and ability to keep the gun out of site, no matter what happens. I'm 5'3" and thusly my pant size limit what I can carry in a smart carry holster. All others are restricted to IWB/OWB as ankle carry does not work with my particular situtation.
I routinely carry a 45 single action army six gun on my person on school grounds and off. Its roughly almost a foot long and yet I can fit that on my person with relative ease. However, I like using the smart carry because in daily activities I am sometimes in situations where the best IWB would be revealed as I become upside down or twisted in some unusual manner, or the shirt/jacket covering it is lifted up.
As to the bersa UC 9mm. Its a fairly good gun. Not my favorite range pistol as it takes constant practice to maintain longer range hits. I personally like having something that I can trust to hit near target even if I am not that accurate for some reason, aka flight or fight and/or shot. This is marginal in my book. The gun feeds well, I have not had any FTF of any kind as of yet. But, I also only feed remington range or up. I have not thrown any russian through it. I like the gun because I can also carry the 17 round magazines for the fullsize one in the compact version. I carry an extra 17 round mag with me at all times in case of mag failure,problems, etc. I personally like the external hammer option to be able to transition from DA to SA quickly. I like the addition of a decocker in situations of carry as I can leave the gun in DA mode safety off for quick contact to threat scenarios. I like the field strip capability of the gun, as I typically end up in environments where a field cleaning can do some good on a gun that requires it more often. Unlike a bit more expensive models. Most importantly it was the most accessible and affordable option at the time I was hunting for a gun to buy.
My cons with the gun: I don't like the price of the magazines. They tend to be much more expensive than other guns. The gun does not take recoil as well as other guns I have shot in the same size and caliber. The grip is personally on the margin of too big for my little hands.
Overall its a decent gun for carry. Its certainly personal choice. I would not have problems personally recommending this gun for someone to carry if they want or were loooking at the model. Its been absolutely reliable to me and fairly faithful. I would start to loose trust in it and my abilities at 25 yards and over, with the smaller barrel. But inside defense ranges its a good gun. Hope that helps.
