Aaron at the Weapon-Blog has released his updated list of contests giving away guns and gun related products for December,
Want to win a nice 1911? There are five contests with 1911s ranging from the Ruger SR1911 to custom guns by Harrison Design and Volkmann Customs. Prefer the Glock? There is a Glock 19 plus the Timberwolf Glock clone.
Can decide between the AR and AK? They have contests with both as well as a number of nice bolt action rifles.
If you do enter any of the contests, please thank Aaron in the comments for providing this service.
