LAZY EYED SNIPER said:The 3" officer's models are definitely a bit more snappy than the full-sized models. There is less frame at the grip to hold on to, making them a little harder to control as well. Even still, they're a pleasure to shoot. Keep in mind that they do have a reputation for being particularly picky with ammo and there is a widespread belief out there that the 3" models are unreliable because of the shorter action. All that said, my Kimber Ultra CDP II has been 100% from the start.
The "commander" length 1911s are a great compromise, offering a full sized frame with a 4" or 4.25" barrel depending on the manufacturer. (RIA uses 4") In my personal opinion and experience, for what it's worth, commander length 1911s are exceptionally well balanced and perfect for both range work and concealed carry.
Thanks for the helpful response (As you always provide). I went and held a few of the RIA 1911's yesterday and I really liked the feel of the tactical model and of the commander model. Both of my pistols are pretty small (S&W 642, Sub-compact XD), so I am kind of feeling the urge to get the full 5 inch barrel. I will probably have to shoot them and see how much the shorter sight radius is noticeable on a 4" barrel.
