I'm a big fan of (good) lasers on defense guns for low light/dark shooting.
All my defense guns (handgun, rifles and shotguns) are equipped with lasers or laser/lights if available for the gun.
For quieter, cheaper laser/light practice I have lasers on several 22 rifles and pistols.
The 22 is a little more neighbor friendly at night that a 9mm, 38, AR, etc.
S&W M&P 15-22.
Beretta 21A. I use this a lot for small semi auto rapid fire laser practice.
S&W K-22 with a Crimson Trace laser.
It's a good big size revolver for laser practice.
I had to mount a rail under the barrel, on this Ruger 22/45, for laser/light practice.
Besides being a larger semi auto laser/light practice gun, it's also handy as a walking around the place at night gun (light).
