Sig Sauer has just announced that their .22LR Rimfire Conversion Kits are on sale starting today until December 8th, 2009. They’ll be going for $249 down from $375, so if you have a Sig Sauer P220, P226, or P228/P229 then this is an awesome deal. It installs just as easily as other .22LR conversion kits as it just replaced the factory slide and magazine. The kit comes with adjustable target sights and will extend your shooting time at the range by a good amount, as ammo is still pretty darn hard to find these days.
