Calibers in each frame Small frame 22 LR (6 shot) 22 Magnum (6 shot) 32 Magnum (5 shot) 38 Special + P (5 shot) Large frame 32 Magnum (7 shot) 327 Magnum (6 shot) 38 Special + P (6 shot) 357 Magnum (5 shot) 44 Special (5 shot) Large frame with pistol calibers 9mm. (5 shot) (discontinued 6 shot) 40 S&W (5 shot) 380 ACP (6 shot) XL Frame (all 5 shot) 41 Magnum 45 ACP 45 Colt It seems to me the best option for overall concealment, capacity, effectiveness, recoil, pressure rating, ammo availability, ammo selection, reload speed, carry options, and continued compliance... is the standard small frame 5 shot 38 Special. Here is what I am thinking and I would like your insight and opinion before I buy. I am mainly only looking at short barrels for conceal carry. Small frames 22 (all) Love this option with 6 shots in a small frame, but I could never live with myself if it wasn't enough to stop the situation. I believe she could control this the best and maintain the most accuracy with this caliber. 32 ( all) I see no advantage for a 32 over a 38 Special. Capacity and size are the same. Large frames I think the small frame is the best option for her. My only concern is that the weight and size will discourage her from continued use on an everyday basis. 32 (all) Same as above. 38 Special Keeping with the idea of matching calibers, I have selected this model as my future carry option. 357 Magnum Ported would not be my first choice, and truthfully since threats from wildlife are very low here in Arizona this would be a ported 5 shot 38 Special in a larger frame. The 6 inch model would be excellent for home defense, but would require a very large and organized purse to conceal outside the home. 44 Special 44 bullets won't shrink, but the ammo selection is low, less available, and more expensive, plus several of the premium ammo manufacturers recommend you Not use their products in a Bulldog 44. 9mm, 40 S&W, and 380 ACP. Reloading speed is my concern with these models. These are really designed to be used as a back up weapon for a police officer. As I understand it, the rounds must each be snapped into place. XL frames This is just to large for her to conceal. The 45 Colt and the 41 Magnum would be a great open carry option in the correct environment.
