Hi extremefishin.
I'm a Colt D Frame fan, so I wish I could recommend them. Unfortunately, they seem to be out of production.
Taurus sounds good to me. I have a PT-22 semiauto (based on the old Beretta M-20 series) that I like. It's reliable, and when the firing pin broke on some Russian steel case ammo, I sent it back and Taurus promptly fixed it and for some reason replaced the stocks, too! It's a fun little gun, double action only, with a magazine safety
that I don't care for, but you may like. Unlike the Beretta versions, the sights are quite usable as well.
Of course a .22 is kinda small, so one of Taurus' revolvers might be a better choice. I would steer away from the lightweight frame materials and the porting. Unless you are experienced, the lightweights might be too much and the porting will probably increase the noise a little bit. A steel 5-shot .38 small frame Model 85 with 2 or 3 inch barrel shouldn't pose too much of a problem, and would be concealable. Start training with target wadcutters and work your way up from there. (My load of choice for my Colt Agent is the Federal Nyclad 125 grain HP "Chief Special" load.)
I'd be careful about buying that SIG 220 too quick. Check it out carefully if you do! I like SIGs as fas as "traditional" double action autos go, but still prefer either the Browning design single action autos or "double action onlies" (DAOs). Also, SIGs seem to have a little more muzzle flip due to their relatively high bore line (compared to a 1911 or Glock).
If I were you, I wouldn't max out my funds on a deluxe semiauto. Instead get something in a less expensive revolver and have money left over for ammo, holster, belt, a couple of HKS speedloaders and a pair of Bianchi speed strips (these carry extra ammo very flat and can be used for tactical reloads).
And don't forget good eye and ear protection!
And the best tactical firearms instruction you can find/afford.
Good luck!
Karl
