I've owned several 5906's and also convinced my brother to buy one of his own. Also I own a few other, similar 3rd generation S&W's.
Once you own a 5906, you'll see why they have almost a cult-like following.
And if you ever shoot a Performance Center version, or a PC "Shorty 40", you will be ruined for most other handguns!
Besides a short list of quality 1911's, the only other guns that I like even close to the 5906 and variants are a couple of Sigs and the Browning Hi-Power. Beretta 92's and M9's aren't too bad either. But the S&W 5906, 4006, 4506, and 1006, trump them all I think.
I just came from the range- I ended up near there by accident while running my daughter to the only Sprint Repair Center nearby that was open... (that's a whole 'nother story!). Anyway, I realized we were close and asked her if she wanted to stop by and shoot. I didn't happen to have any of my .22's or my 5906's, but was carrying my S&W 4014 in .40 S&W of course. I rented her a Browning Buckmark (a brand new one- very sweet! I have a much older one) and she proceeded to shoot about 100 rounds and shot very well for a 14 year old!
And I shot 50 rounds of Federal range ammo and just continue to be amazed at what a great shooting little compact pistol it is, and at the tights groups I was getting.
I'm not a snob and try to find something to like in most quality pistols. But the 5906 is just one of the best shooting, rock solid, iconic pistols.
They remind me of some kind of combination of a Ford F150 or a BMW 5 series sedan. Dependable, rock solid, and each time you use one it seems more enjoyable than ever before.
