Car Keys maybe? This is Canada, while I support CCW, I don't actually feel the need/want to carry here.
If I had to carry because the world/Canada changed to something much more randomly dangerous, I would want the Ruger SP101 357 Mag, 2.25″ Revolver:
The Ruger SP101 revolvers fitted with the Crimson Trace LG-111 Defender Series Lasergrips are designed to put the shooter on target quickly and accurately. The Ruger SP101 model KSP-321CT has a spurless hammer for snag free carry and draw, features 2.25 inch barrel and fixed sights. These 5-shot stainless steel revolvers are chambered for .357 Magnum and can also fire .38 Special ammunition, including .38+P cartridges.
The Crimson Trace LG-111 Defender Series Lasergrips are constructed of hard durable polymer. The red beam laser is activated by a pressure switch located on the front of the grip, making it instinctively usable for right- or left-handed shooters. The laser is adjustable for windage and elevation using an Allen wrench (provided).
You Can Never Be Too Prepared. The SP101 revolver boasts the strength to handle the powerful .357 Magnum and .327 Federal Magnum cartridges in a controllable, small-framed double-action revolver. Among the most powerful small-frame revolvers on the market, they are engineered for solid performance. Featuring a recoil-reducing grip, the SP101 is comfortable to shoot and perfect for personal defense or field use.
Strong and reliable shot after shot, all SP101 revolvers boast solid steel sidewalls (no side-plates), making them rugged, reliable, and dependable. Available in .327 Federal Magnum, .38 Special and .357 Magnum (which also accepts the less expensive .38 Special cartridges), you can count on the SP101 when you need it.
