One salient fact about wheelguns- their springs are not under compression until the hammer is cocked (single action mode), or the trigger is pulled for double action firing. If you have any qualms about s recoil spring failing in your defensive handgun, don't screw around any further- get a Kimber 1911-A-1 series in .45ACP- and blow the living dogshit at CQC range any intruder who makes the mistake of breaking into your castle. I sleep every night with a similar piece in "locked, cocked and ready to rock" under my pillow-if trouble comes through my front door, well you can finish that scenario any way you wish to. RWTF
Interestingly both you and HomelessJoe seem to rely on same brand of handgun.
I live in typical house. My two HD guns are Ithaca 37 Turkeyslayer w/skeet choke in 24" barrel with Winchester #1 BK @ 1250fps secondary weapon is Colt M45A1 loaded with low flash 230gr subsonic JHPs. What I need is advice on close quarters personal defensive handgun. Unfortunately there are just two choices S&W 940 or the R9.
