My PT945 is my Winter House and Carry Gun.
It's been excellent in reliability, but your hand must fit it! Try to get to shoot one before buying, if possible. Mine will beat up the top of my grip hand if I am not careful to hold it lower. Have considered some modification (BeaverTail Removal). Consider also a PT24/7 in .45 ACP.
BTW, for holsters I have a Kydex Glock 21 IWB holster and a Fobus HK-1 Holster that fits the PT945 perfectly.
