Couple of years ago I bought my first .45. It was a full size P250 .45. Also ordered 2 extra mags for it. It shot pretty good, ate anything I fed it but is was a little big for conceal carry all the time especially in the warm southern states were I wear shorts almost year around. Didn't really know about x-change kits at that time. Traded it in, took a heck of a loss when I bought my Ruger SR1911. That part wasn't a bad move because I love the 1911. After about a year I had a need for a smaller .45 for concealed carry buy wanted something that held more than 5 rounds. Two pistols seemed to fit the bill. The Sig P250 compact or Taurus P145 Pro. I wanted the Sig but couldn't find one heance I bought the P145 Pro. I really wanted the double action Sig. Had the P145 Pro for about 4 months, it shot very good but about 2 weeks ago found a Sig and traded the P145 for the Sig. I now have the P250 .45 compact Sig and I am very happy even if it took about $600 to learn my lesson.

I have the Sig P250SC 45 and its great. It even fits in my Nemesis pocket holster. Which my P290, Kimber Solo, P250 SC 9mm do as well. The P250 SC 45 is a little thick, but so am I.

Get yourself a Sub compact 40 or 45 exchange kit. I think you'll be happy with either one.

Go for it!!

I had a Taurus PT140 Millennium Pro. It was the 2nd generation- not the original Millennium (without Pro in the name), but the first gen of the Pro series. It was a true DAO before they switched to the odd SA/DA system. Anyway, I still have it, but speak of it in past tense because it hasn't worked for several years and haven't yet sent it out to Taurus for repair.

I used to love the gun. It was reasonably accurate (I used to think it was great on accuracy for a subcompact or smaller compact, until I started shooting other small guns), it was very reliable (until it broke ), it was comfortable to shoot, and it is small and light enough for comfortable carry. Through a thousand or two rounds it had only a couple minor hiccups, until it finally broke in such a way as to make it useless and would have been a catastrophic failure in a self defense situation. The firing pin is locked forward (I'm lucky that when it finally chambered a round it didn't go off). Usually that keeps it from chambering, though there have been a few exceptions where it will chamber and fire the first round. Something that catastrophic and potentially dangerous definitely soured me on the gun.

I also have a .45ACP P250 Compact. Love that gun, very accurate (for any size), comfortable to shoot, small enough to carry, it is my "just right" gun. 10 rounds (9 in mag, one in the chamber) of .45ACP is quite comforting. It has been 100% reliable.

That is to say, I think you made the right choice.
