Just a few notes and opinions:
No weapon is effective if it is not kept clean and serviced regularly. Read the owners manual.
IMHO a revolver should fire if the cylinder turns and the hammer is not too light or filed off. They are more reliable than a semi-auto and less likely to jam or misfire. If you do not hit your target in three shots or less then you are less likely to survive the encounter. Most encounters here in the states will have one or two targets at most, 17 round clips are not necessary and add weight that could slow reaction time.
I like the Colt double and single action revolvers in .45 or .357. That is my opinion and is worth just that. The Cobra, Colt .38 Special, is easy to carry, reliable, and point and click in use. I like the design of the Browing Semi-autos as they fit my hands better and seem to be better tooled. The Ruger I used to have worked well for many years and thousands of rounds, it is still going strong. Cleaning is the key. My wife's Glock is her second favourite, never an issue but we keep it very clean.
Hydro-Shocks are supposed to be very good at delivering the energy of one round to the target. The idea is for the round to expend it's energy in your targe. A full metal jacket will continue on to the next item in line.
If concerned about rounds going through walls look into this company: New Tech Ammo (
www.newtechammo.com or
steve@newtechammo.com ) Their rounds will not pass the second layer of drywall and they do expend their energy into your target. They have a wide selection of calibres.
