That was just one of the reasons why I adopted the Glock 20 as my wilderness sidearm, even though it’s a significant reason. The polymer frame features a built in rail for a light or laser attachment. A $125 Streamlight attaches in seconds, or can be removed and attached to my Remington 870, 450 Marlin, or 16” Marlin 336 in seconds.
The other reasons are:
* A Glock 20 is a bargain. I bought mine new for $550. Add a light, tritium sights, comfortable IWB holster, cheap chest/bandolier holster, and four more magazines, and I was still under $1000.
* The 10mm cartridge packs energy beyond that of the 357 mag, and nearly that of the 41 mag
* The weapon is loaded with 16 rounds, and a quick magazine change provides 15 more
* It’s significantly lighter than my S&W 629, even loaded with so many rounds, and it’s less bulky, too
* It has a smooth DAO trigger that is easy to shoot well
* Ammo selection is excellent, from anti-personnel Hornady Critical Defense to hard cast from Buffalo Bore and Underwood to FMJ ball
* I carry an Underwood FMJ ball round in the pipe, and a quick magazine change specializes the next 15 rounds from anti-personnel to anti-bear/moose
* And perhaps most important, it is easy and cheap to install top quality tritium sights
