Re: Home defense pistol for my Mom?
Home defense for a 60ish female with arm strength issues was the original question right?
WADR...Light weight and short barrel = harder to shoot well (more felt recoil and shorter sight radius) for no good reason when used in the "home defense" role. Carry and concealment are not the issue, simplicity of use and recoil management are. Avoid the small lightweight "cute" guns.
Find a medium (K) frame, 4" barrel, 6 shot, fixed sight, ex-police service revolver, such as the S&W M10HB or S&W M65. Most are used but not abused and have been shot enough to smooth the action. I'd much rather have a smooth trigger than a light one. There are plenty of grip options available to fit her hand and/or mitigate recoil.
Paint the front sight a bright color such as orange or yellow so it stands out in reduced light and serves as a reminder to focus on the front sight for the normally short range home defense distances a 60ish female might be forced to use the revolver for.
Learn to shoot with mild mannered mid-range .38Spl. 148HBWC (some folks even use'em for SD on the assumption that "good hits first" is best and that the WC does at least cut a full caliber hole...that bleeds). She won't get beat-up during practice, making it more likely she'll enjoy shooting, and that will make it more likely she will continue to practice...the most important element to becoming effective with any weapon.
Load it with any of the better SD HP loads...When she's ready.
Periodic practice with the HBWCs, finishing with a cylinder of the SD load, aught to make/keep her comfortable enough to keep at it.
Again, WADR...A round gun makes much more sense than a square gun for this ladies particular application with her arm strength issues that impact her ability to run the gun. A lack of arm strength is also frequently indicative of future limp wristing. Square guns require a firmness of grip/hold for the slide to work against to avoid malfunctions.
Just my .02 added to the kitty...
BTW NH...
