I own the 45 full frame, overall I'm satisfied. I put on a pachmayr pull over grip for a bit of comfort, did the trick. The adjustable sights were a great touch and I am a fan of how it doesn't go into single action when racked, I like to carry in double action for safety.
1)Out of about 700 rounds I had one fail to feed, I emptied the last 6 of my tulammo into the mag and loaded the other half with wwb, it caught on the ramp with the first wwb when transitioning.
2)Might just be mine, but if I'm not careful when I take the safety off and push it too far down before releasing, the spring for the decocker can slingshot the safety right back into the on position. I've had to teach myself to not push the safety with a lot of force. Try it out when holding one for yourself.
3)A lot of my buddies HATE the trigger, it's not for everyone.
It's a decent gun, was a perfect fit for my budget at the time and given the choice I'd probably choose it again.
