my personal choices are as follows:
1. AR15 or clone w/ an AimPoint CompM (I use a BushMaster V-Match flattop w/ standard handguard)
2. Berreta FP1201 w/ SureFire 6P forearm light
3. Glock 23 for "normal" concealed carry, with a behind the hip holster w/ concealing shirt or jacket, or carried in a ****** bag (fast action gun) for the PC folks
4. S&W 442 for deep concealed carry (ankle rig or pocket carry)
Why those choices???
1. A tactical carbine is easy to handle, is relatively powerful, and can be used from 0 to 300M with good accuracy. The Aimpoint w/ 4MOA dot allows me to get on target extremely fast, yet will still allow for precision shot placement at longer range. With lightweight varmint bullets, (40, 45 grain) home protection use is viable. These rounds will not easily over penatrate - they break up on light weight materials like drywall or wall studs.
2. A 6-1/4 pound 12 guage w/ 3 rounds of 00 followed by 2 rounds of slug for general outdoor protection or 5 rounds of slugs for dangerous game protection (think Salmon season). There is a serious problem w/ over penatration w/ either of the above loads in a home use situation. As a rule I use #4 buck as a home defense load.
3. Glock 23 - 13 rounds standard mag for CCW, plus a 15 round G22 mag as a spare. If the situation can't be solved with that, your in serious doodoo. Sized between the G22 and G27, it offers good concealability with a large capacity magazine. I prefer to carry in a MadDog behind the hip Kydex holster. Malfuntions are rare, but generally are easily solved by the tap, rack, flip method.
4 The good ol' alloy S&W 442. I consider the 38 Special and 380 ACP to be the minimum effective rounds for CCW carry. A DAO revolver is still an effective fighting handgun if you train with itand understand how to solve them. Simple to use, a simple mafluntion just requires another pull of the trigger to get it going again. The worst possible malfunction is getting a case stuck under the extractor, but with practive it can be cleared quickly. I carry a speed strip or a two by two pouch for reloading. A full speed loader is also an option, but the other two allow you to keep the gun full without dumping out loaded rounds.
I've been fortunate to live in the Prescott, AZ. area. We are home to Col. Cooper's GunSite, Chuck Taylor's ASAA and Mark Fricke's AFTT. All top notch schools, and I've had the opportunity to train with all of them over the years. Chuck Taylor's instruction was perhaps the most informative for me, and I use his techniques and ideas the most.
