FYI..dovetails in SIG pistols are all dimensionally the same. I put the sights I bought on my P229 SAS. The difference in them is the height corelation of the front and rear sights. I changed the barrel to 357SIG and the P229 which comes in 40 cal uses different height sights than 357SIG chambered pistols. I recommend that a gunsmith install them unless you have adequate facility and tools and ability to make an acceptable sight press.
Pros: coolness... lighted front and rear at night/ as good as a laser
Cons: VERY tight fit in dovetail
