Sig Sauer Introduces .22LR Rimfire Conversion Kits for the P220, P226, and P229 Pistols

Sig Sauer has announced the kits will start shipping in limited quantities in early April 2008. MSRP will be $369.00. ***
Exeter, New Hampshire - SIG SAUER, a world leader and manufacturer of firearms for law enforcement, military, government, and civilian markets has expanded its line of accessories to include a .22LR Rimfire Conversion Kit. SIG SAUER’s new Rimfire Conversion Kit saves on ammunition costs and hones your shooting skills. By training with the .22LR Rimfire Conversion Kit, the shooter can practice more while retaining muscle memory and feel of their favorite duty pistol.
The .22LR Rimfire Conversion Kit is available for the SIG SAUER P220, P226, and P229 models and feature a black hard coat anodized slide, machined from solid aluminum billet. Offered as a complete replacement assembly, the Rimfire Conversion Kit installs as easily as field stripping the pistol. Simply remove the standard slide assembly, install the “new” .22 slide and barrel assembly, and add the included .22LR magazine and you’re ready for the range.
The Rimfire Conversion Kit features adjustable target sights and comes complete with a hard carry case.

If it is accurate, and it probably is, then that is not a bad price, about the same as a Marvel conversion as I recollect. They don't talk about the sights on the new slide. Fully adjustable or do you need a $100 tool to adjust it?
